Do you know what the best protective material is?

Kevlar is the registered trademark for a light, strong para-aramid synthetic fiber, related to other aramids such as Nomex and Technora.

Developed at DuPont in 1965 by Stephanie Kwolek it was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components.

Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body armor because of its high strength-to-weight ratio—famously: "...5 times stronger than steel on an equal weight basis

When Kevlar is spun, the resulting fiber has great tensile strength (ca. 3 620 MPa), and a relative density of 1.44. When used as a woven material, it is suitable for mooring lines and other underwater applications.

There are three grades of Kevlar: (i) Kevlar, (ii) Kevlar 29, and (iii) Kevlar 49. Typically, Kevlar is used as reinforcement in tires and rubber mechanical goods. Kevlar 29's industrial applications are as cables, in asbestos replacement, brake linings, and body armor. Kevlar 49 has the greatest tensile strength of all the aramids, and is used in plastic reinforcement for boat hulls, airplanes, and bicycles. The ultraviolet light component of sunlight degrades and decomposes Kevlar, a problem known as UV degradation, and so it is rarely used outdoors without protection against sunlight.

Kevlar is well-known as a component of some bullet resistant jackets and vests. Actually Stephanie Kwolek (born July 31, 1923) is an American Chemist who invented poly-paraphenylene terephtalamide—better to be known as “Kevlar”. It has varied uses and is being used by many diverse industries in world but our concern is its use regarding as safety clothing, especially in the areas which padding such as shoulders, back and elbows.

Lightweight and flexible it is, Kevlar has evolved over four decades of innovation and technology and it has all to do everything from helping to save thousands of lives around the world; making their ridings safer and better protected. If it needs to be light, strong and nonparallel safe, it must be “Kevlar”.

It is now being used for motorcycle jackets. A Kevlar motorcycle jacket has a lot more merits than other riding jackets. Unlike Leather jackets they don’t give hard time in scorching summers, and are far safer in case of unexpected accident. Icing on cake is that these are easier to maintain, even easier than leather jackets. One would definitely need to buy a protection and cleaning solution to maintain and polish leather jackets. Leather jacket may also need professional cleaning once after some time but a Kevlar motorcycle jacket can easily be cleaned in a washing machine, any time.

Coming towards benefits of a Kevlar motorcycle jacket; for a polymer, Kevlar has very good resistance to high temperatures, and maintains its strength and resilience down to cryogenic temperatures like (-196°C); indeed undoubtedly, it is slightly stronger at bit low temperatures.

One of the first benefits of a Kevlar is that they're great to wear during hot weather. Other materials such as leather are too warm to wear when the weather is hot outside. Kevlar breathes better than nylon and leather, so they are more comfortable to wear during hot weather.

No one ever wants to face any accident while their riding. Unfortunately if you ever do down sliding on the asphalt while wearing any other polyester, you are likely to have permanent skin damage. Fact behind this general idea is that in actual polyester has a low melting range and poor abrasion strength, so because of the high fraction with ground/surface, it may melt into your skin, also you will be bruised all over.

And on contrary a Kevlar riding jacket is much safer to wear; beyond the words. It has high abrasion and fraction resistance strength and an extremely high melting range, so it won't melt into your skin; if something unseen and unfortunate comes……………….

A.P. Physic's Questions?

1. An elevator has a mass of 1400kg. What is the tension in the supporting cable when the elevator traveling down at 10m/s is brought to test in a distance of 40m. (Assume a constant acceleration.)

2. A jet airplane accelerates on the runway at 3.0. It has two engines which exert a total thrust of 3.0 x 10 ^ 5 N. What is the mass of this airplane?

3. Many people are familiar with the face that a rifle recoils when fired. This recoil is the result of action-reaction force pairs. A gunpowerder explosion creates hot gases which expand outward allowing the rifle to push forward on the bullet. Consistent with Newton's third law of motion, the bullet pushes backwards upon the rifle. What is the acceleration of the bullet relative to the recoil of the gun?

1. brought to ... rest by cables I suppose.
