Rubber bands are worthless and unreliable. They cannot be trusted to repeat a performance even under identical conditions. If one decides that they will risk a grade on the reliability of a rubber band‚ they are setting themselves up for dire results and disappointment. The assignment was to create a small car‚ built mainly from cardboard‚ powered by rubber bands. The rubber bands were wound tightly around an axel. After the car was released‚ the elasticity of the rubber bands would pull the

Karol Mooshe Literature Review Rubber vs. Rubber The purpose of my experiment is to figure out which type of synthetic rubber is best to use on bicycle tires‚ neoprene‚ latex‚ or silicone. Synthetic rubber is a polymer. A chemical compound that includes many molecules that form one large molecule. Synthetic rubber is also an artificial elastomer‚ a material that undergoes elastic deformation under stress‚ but then turns into its original shape. In

What is a Tyre? • Pneumatic tyre is a flexible‚ toroidal‚ compressed gas (normally air) container mechanically attached to the outer circumference of rim of a vehicle wheel. The name is derived from “Attire” – a protecting covering or coat. • The rubber exterior of a pneumatic tyre is merely a flesh for a skeleton of fabric; this skeleton and the manner in which it is constructed are of fundamental importance in establishing the tyre’s characteristics. • A tyre is an integral component of a vehicle

There seems to be no rationale behind the hiring of Line foreman even though it’s a very crucial position. This is evident that the transfer and internal hiring is very much influenced by the union and not on merit; there is a preference on quantity over quality. This policy is demotivating other potential workers in the company as they don’t see a chance of future career growth. . The externally

ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various bacterial
