Rubber Tire ( car ) Research Paper Example | Topics and Well Written Essays - 1000 words

Rubber Tire ( car ) - Research Paper Example The materials can be stretched severally to almost double its original size, and upon being released, it will return almost to its original length. Rubber can be produced from two basic raw materials, natural rubber or synthetic rubber. With the objective for improvement, in accordance with customer and regulatory requirements, how a car tire chemical composition is reported through the IMDS system. The introduction of IMDS brought about introduction of pseudo-substance basically for tire. Guidance document clarifies how the pseudo- substance should be used in the IMDS system in order to describe the chemical composition of tire. Production of car rubber is classified into two basics steps, production of rubber itself and processing into finished goods. In the first step of rubber production, it can be produced naturally by use of an agricultural crop or synthetic rubber made from petroleum products. Natural rubber is acquired from the rubber tree (Hevea brasiliensis) as latex. This is a runny, milky white liquid which is tapped from the bark of rubber tree. Latex is a colloidal dispersion of solid particles of the polymer polyisoprene in water. The molecules of this compound are loosely joined making long, tangled chains. These molecules of chain when pulled apart untangles easily but springs but together once released and this brings about the characteristic of rubber being elastic. Many tanks are used to collect latex, blending the yield of many trees. (Wiley) General Natural car rubber currently accounts for about 30% to 40% of the total elastomeric part in a car tire, but in the case for a truck is 60% to 80%. The procedure of recovering this natural rubber from latex involves a process called coagulation. This process is carried out by adding acid such as formic acid (HCOOH). Coagulation takes about 12 hours. The coagulum, which is now soft solid slabs, is then squeezed through a series of rolls which removes most of the

Investigating the relationship between personality and Leadership Essay - 1

Investigating the relationship between personality and Leadership - Essay Example For example, Theory X and Y of management may be used within the same company in different departments depending on the nature of the work involved. Theory X of management assumes that most people have personalities that dislike work and must be controlled by strong means if they are to remain productive. Further, people need direction as well as control and not independence while they work (NetMBA, 2005). Theory Y is the complete opposite of this since it suggests that people are naturally inclined towards work as they are towards play and rest. Additionally, people find satisfaction in work and will use imagination, creativity and their personal skills to solve work related problems if they are allowed to work as they please (NetMBA, 2005). A manager who has a personality which is a good fit for managing with Theory X would find it difficult to create productivity in a department which should be governed with Theory Y. In such situations, personality itself can be defined as the collective emotional, thinking, and action patterns which are exhibited by an individual which are more or less consistent over a period of time (Miner & Dachler, 1973). Psychologists and those who study human personality have defined types of personalities and presented theories which help in placing individuals on certain scales of personality (Joy, 2004). The idea of personality as a set of individual levels of certain traits is fully supported by Cattell (Statt, 2004). It is also suggested that there are quite a few elements which affect human personality and the interaction of these traits as well as the reactions they produce to various stimuli result in a fully formed personality (Plucker, 2007). The work done by Cattell is important for the study of personality and productivity since it lets us gauge an individual’s personality and then connect it to their performance at a given position in the company. At the same time, we have
