Some projectiles are made entirely of lead. Bullets are made of a variety of materials such as copper lead steel polymer rubber and even wax.
7 Things You Didn T Know About Ammo Gohunt
Since lead is a very dense material bullets made of inexpensive non toxic materials will be lighter than bullets made of lead unless bullet length is increased.
Are bullets made of lead. There are many other materials that are used in bullets today including aluminum bismuth bronze copper plastics rubber steel tin and tungsten. Bullets are made of a lead alloy often containing tin and antimony. Non lead bullets routinely retain 98 of their weight.
When a lead bullet is recovered it is routine to find them weighing 65 75 of their original weight. Lead is likely the most common material in bullets. Increasing bullet length may require a faster rifling twist to maintain stability.
One example of this is lead round nose bullets. Some bullets have a thick jacket of copper over the out side for improved performance. Lead is an inexpensive metal that is soft and dense 3 criteria for bullets.
The one everyone is aware of is they are not made of lead and they are safer for scavengers who feed on the gut pile. Lead or a lead alloy typically containing antimony is the traditional bullet core material. Cases are made of brass steel or aluminum.
Some have lead cores like full metal jacket rounds which feature lead wrapped in copper or a similar hard metal. The biggest benefit to performance is weight retention. The most direct solution is switching to lead free ammunition or at least jacketed bullets which have a lead core covered with a coating made of copper or nylon.
Traditional bullet jackets are made of copper or gilding metal an alloy of copper and zinc. A bullet is a kinetic projectile and a component of firearm ammunition that is expelled from a gun barrel during shooting the term is from middle french and originated as the diminutive of the word boulle boullet which means small ball. In this clip from discovery channel s howstuffworks show find out how lead is used to manufacture bullets.
Most will be made of lead if not entirely they will have a lead core covered by another metal such as copper. Brass is the most common. Lead has been traditionally.
Inferior external ballistics cause lighter bullets to be less effective against distant targets.

The History Behind Crayola Crayons
Crayons are made from paraffin a waxy substance derived from wood coal or petroleum.
How do crayons work. Types and uses of crayons. Wax crayons differ from pastels in which the pigment is mixed with a dry binder such as gum arabic and from oil pastels where the binder is a mixture of wax and oil. Friction and the heat produced play a small role but the crayon would probably still lay down material without friction heat because of the physical nature its relative softness of the crayon base at room temperature.
Crayons are available at a range of prices and are easy to work with. Artwork can be created by melting crayons or using fabric crayons which melts crayons to fabric surfaces. Charcoal hard and soft clay pastels oil pastels water soluble and grease pencils.
It s then mixed with pigment and a strengthening additive. A crayon or wax pastel is a stick of pigmented wax used for writing or drawing. Specialty crayons color cardboard glass leather clothes plastic metal stone and wood.
The operator uses hydraulic pressure to eject the crayons from the mold. Paraffin was produced commercially by 1867 and crayons appeared around the turn of the century. Fine artists and glass makers use these crayons.
Cool water 55 f 13 c is used to cool the mold allowing the crayon to be made in 3 to 9 minutes. A single mold makes 1 200 crayons at a time weighing a total of about 40 pounds. How crayola crayons are made paraffin wax is heated until it melts into a liquid.
The early crayons were black and sold mainly to factories and plants where they were used as waterproof markers. After coloring a picture with these crayons brush on water for a watercolor effect. They are less messy than most paints and markers blunt removing the risk.
These techniques demonstrate artwork that can be created with the crayon labels torn off. The paraffin wax and stearic acid are susceptible to being transferred to a substrate when pressure is applied and the crayon is moved over the substrate. Try these techniques to create different effects.
Pumps move that colored liquid into water cooled steel molds with 110 crayon shaped cavities. Water soluble crayons dissolve in water and have high pigmentation. The liquid is poured into a preheated mold full of hundreds of crayon shaped holes.
Crayons other than wax are.

A good fly can make or break your fishing adventure so be prepared with our list of the twenty best flies of all time. However unlike either of the other two types of flies streamers do not resemble insects. Mayfly nymphs are divided into four groups.
Clingers swimmers burrowers and crawlers. Streamers like nymphs are most often fished below the surface. Imitators flies that imitate a living creature found in nature like an ant attractors flies that don t imitate anything in particular but merely attract a particular type of response from fish more about imitators and attractors.
These little creatures have 2 or 3 tails long legs and short antennae in their bodies. Make sure you know what s what and make sure you catch the biggest fish in the pond. The nymph is one of the most productive flies in fly fishing.
In order to play the game effectively though you need to have a basic understanding of the different types of fly fishing flies.

Some monomers on the other hand are synthetic. Glucose and related sugars.
Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization.
What are monomers made of. Each monomer may link in different ways to form a variety of polymers. Four types of nucleotide monomers are precursors to dna and four different nucleotide monomers are precursors to rna. Glucose vinyl chloride amino acids and ethylene are examples of monomers.
Nucleotides which are found in the cell nucleus polymerize to form dna and rna. The essential feature of a monomer is polyfunctionality the capacity to form chemical bonds to at least two other monomer molecules. Monomers may be classified as hard soft or reactive based on the properties they confer on the final polymer or copolymer.
Polynucleotides are long polymers made up of linear arrays of monomers called nucleotides consisting of nitrogen bases pyrimidines and purines linked to sugar phosphate. Nucleotide monomers are found in the cell nucleus. Sometimes polymers are made from bound groups of monomer subunits up to a few dozen monomers called oligomers.
A common man made monomer is vinyl chloride. Glucose and related sugars. For polynucleic acids dna rna the monomers are nucleotides each of which is made of a pentose sugar a nitrogenous base and a phosphate group.
Amino acids for instance are natural monomers that can polymerize to form proteins. Monomer a molecule of any of a class of compounds mostly organic that can react with other molecules to form very large molecules or polymers. In the case of glucose for example glycosidic bonds may link sugar monomers to form such polymers as glycogen starch and cellulose.
Names for small monomers. Hard monomers are for example methyl methacrylate styrene and vinyl acetate. The monomer units of dna are formally called deoxynucleotides.

Couldn t find anything on it. To make duct tape the fabric is covered in melted polythene which protects it from moisture and erosion.
Despite duct tape s reputation for superior adhesion testing done by independent researchers has found that the tape does not work as well as it is intended to.
Where does duct tape come from. Underneath that there s a middle layer made of fabric while the bottom layer is a rubber based glue. In fact a roll goes up on every flight that leaves the launchpad. Duct tape is typically made from three different layers.
Today i found out duct tape was originally named duck tape and originally only came in green not silver. It was very well done and got into a very detailed discussion about the discovery of the duck tape bush by native americans and the peculiar properties of the bark and the sticky sap of the bush which imparts the tape s adhesive qualities. The duct tape adheres to the top layer of the wart.
It s no secret that duct tape is an important tool to the nasa program. This may be less painful than remedies like freezing. Duct tape has actually saved lives and equipment in space.
These images and stories were gathered by the duct tape guys from the pages of nasa s web site. Duct tape was originally invented by johnson johnson s permacel division during wwii for the military. Duct tape two pringles lids.
The military specifically needed a waterproof tape that could be used to keep moisture out of ammunition cases. The ultimate wide scale adoption of duck tape today generally referred to as duct tape came from vesta stoudt an ordnance factory worker and mother of two navy sailors who worried that problems with ammunition box seals would cost soldiers precious time in battle. The top layer which is exposed is made from a plastic called polythene.
When you tear the tape off a layer of the wart will often come off with it.

What s in a tire. Different versions are used depending on the section of the tire being constructed along with the manufacturer s specific performance requirements.
What Are The Different Parts Of A Tire Completely Firestone
The materials of modern pneumatic tires are synthetic rubber natural rubber fabric and wire along with carbon black and other chemical compounds.
What are tires made of. Bicycle tires aren t made from just one type of carbon black or silica though. The other primary ingredient in tire rubber is carbon black. They consist of a tread and a body.
Bead tire bead bundles usually strands of wire secure the tire to the wheel. Tire tire tire materials. The tire is the only part of the car that touches the road.
To this end cord materials must have high stiffness resistance to repeated flexing high strength to weight ratio and good adhesion to rubber. The first component to go on the tire building machine is the innerliner a special rubber that is resistant to air and moisture penetration and takes the place of an inner tube. Synthetic rubber is produced from the polymers found in crude oil.
Common softeners antidegradants. How is a tire made. A pneumatic tire is reinforced by layers of relatively inextensible cords that hold the air pressure and restrict deformation and growth of the tire during use.
Tires must strike a balance between traction comfort durability energy efficiency and overall cost. Passenger tires are usually made with two or three belts. The tread provides traction while the body provides containment for a quantity of compressed air.
Plies and belts give the tire strength while also providing flexibility. The tread is a thick extruded profile that surrounds the tire carcass. Take for instance a smart phone.
As a result of these competing needs tires are more complex to design and build than you might think. Carbon black is a fine soft powder created when crude oil or natural gas is burned with a limited amount of oxygen causing incomplete combustion and creating a large amount of fine soot. Tires contain many rubber compounds and other materials because they are required to safely perform in the face of a wide range of demanding conditions.
Tire cords have been made of cotton rayon nylon polyester. Next come the body plies and belts which are often made from polyester and steel. Tread compounds include additives to impart wear resistance and traction in addition to environmental resistance.
Tread compound development is an exercise in compromise as hard compounds have long wear.

Who invented the watch and clock. The first mechanical alarm clock was invented by american levi hutchins of concord new hampshire in 1787. People also called these watches the nuremberg eggs because of the oval enclosure. Then it happened at the beginning of the 16 th century.
The german peter henlein from nuremberg made the first portable clock with a spring mechanism. After sundials and obelisks clocks were invented. This crude device which often lost several hours over one day of work proved to be instrumental starting point for other inventors who quickly focused their minds on solving the problem of creating small sturdy easy to use and most importantly precise clock.
The first mechanical watch. The timekeeping mechanism in these early pocketwatches was the same one used in clocks invented in the 13th century. The swiss mechanics jacob zech and gruet changed this with their innovation.
Watches have come a long way from sundials and obelisks used by ancient civilizations to try and keep accurate time. At the time they were considered one of the greatest technological accomplishments. The first modern day clock was invented by a locksmith.
The origin of the watch. The watch was wound and also set by opening the back and fitting a key to a square arbor and turning it. Historically speaking fist modern clock was created by german inventor peter henlein who introduced to the world spring driven clock around 1511.
However peter invented the clock watch in 1505 in england. It was still an art to let the mechanical watch run accurately. After years of calculating time using the movement.
This is seen as the first watch. After this the pocket watch was invented and round 1650 individuals used to roam round with clocks of their pockets. Even though pages of history have forgotten about many watchmakers and innovators before him modern scientific community has accepted that peter henlein clockmaker from the nuremberg germany is the father of the modern clock and the originator of the entire clock making industry that we know today.
However the ringing bell alarm on his clock could ring only at 4 a m. As far as records are maintained in the history the first clock by henlein was made in 1510 and by 1541 he was well known for his art and was called in different parts of europe. This video will walk you through with when and who invented first watch first mechanical watch.
It was solely after peter hanley s invention of the clock watch that switzerland s joss bergie invented the minute needle clock in 1577. 183 725 by seth e.

An aerosol can contains one fluid that boils well below room temperature called the propellant and one that boils at a much higher temperature called the product. Overall the prospects for this propellant are promising.
Aerosol Spray Wikipedia
In aerosol spray cans the propellant is simply a pressurized gas in equilibrium with its liquid at its saturated vapour pressure.
What are aerosol propellants. Types of aerosol propellant gases the production of aerosol propellant gas is divided into. For vehicles the term propellant refers only to chemicals that are stored within the vehicle prior to use and excludes atmospheric gas or other. Used to propel solid objects.
Scientists soon discovered however that cfcs like freon being used in these cans contributed to ozone depletion. Technically the word propellant is the general name for chemicals used to create thrust. Gts aerosol propellants are odourless.
It is used with a can or bottle that contains a payload and propellant under pressure. This new propellant has impressive credentials in that it is not a voc has a low gwp and is considered non flammable under dot definitions. Aerosol spray is a type of dispensing system which creates aerosol mist of liquid particles.
Types of propellants used in aerosol cans when first introduced commercially in the 1950s until the late 1970s aerosol cans used chlorofluorocarbons known as cfcs for short as the propellant used to spray various products. Gts supplies customized pure products and mixtures at different pressures to satisfy all of its customers industrial or productive needs. As some gas escapes to expel the payload more liquid evaporates maintaining an even pressure.
The product is the substance you actually use the hair spray or insect repellent for example and the propellant is the means of getting the product out of the can. Aerosols are only different type of packaging i e they are pressurised dosage forms containing one or more active ingredients product concentrate propellant which upon actuation emit a fine dispersion of product concentrate in a gaseous medium. When the container s valve is opened the payload is forced out of a small opening and emerges as an aerosol or mist.
