Known as one of the most versatile quality polymers, Polyurethane gloves are in huge demands at the consumer end. Well, what are the qualities that make a Polyurethane glove the best? To be honest, you can't find much stronger grip (and no sticky sensation) in a glove made by Polyurethane than any other material. The other qualities of this material are…

The resistive component of analysis can also be modeled as a spring in which the spring constant is positively correlated to the force applied to the spring: F= kx, where k = f(x)*Fimpact. The force of impact would mostly dissipate through the springs, and the specific behavior of the springs can be modeled in later stages. The component of force that needs to be looked at primarily is the x component, since this is the component of the force that would produce the most torque on collision.…

Bows , the weapon of champions. Bows have been the choice weapons to defend the front lines of battle and to guard the castles of kings and queens.

there are much safety kept in the form clothing, noise control, temperature and electrical control. For the aircraft there are fabrics for fire safety and precaution like Nomex, Kevlar and PBI. For fire safety and protection at high temperature PBI is the most preferred as it is the engineered blend of Nomex and Kevlar (Jackson, 1999). Protection against several environmental factors like temperature, freezing, rain must be adequately subjected. Icing is the oldest problem and is one of the…

are important in the field of organic chemistry, because they can be changed to create different compounds used in everyday life. Polymers can be found in nature, such as starches, proteins, and cotton. They can also be man-made, such as plastics, Kevlar, and Teflon1. Polymers can be linear, branched, cross-linked, and network1. Polymer are used in medicine, consumer sciences, industries, and sports1. Properties of polymers can be altered by chemicals and structural changes and how the…
