* Recycling everything that you can recycle! This may mean you have to spend an extra five minutes sorting out what is rubbish and what is recyclable. This may mean a different bag to put your recyclables in. * Recycle your unwanted gadgets. There are websites that recycle your mobile-phone and you can even receive money for doing so! * You can recycle your used printer ink cartridges. So many used ink cartridges are disposed of by households and business every day and these are unnecessary

Activity 2.6 – Aerodynamics on Arrow Arrow would be my aerodynamic example. Its has a very long history, we can start from the stone age till present. Arrow from back then was made by bones or stones for the head (projectile point) and wood or bamboo for the body (shaft). Now, we have tungsten or stainless steel for the projectile point and aluminum or carbon fibre reinforced plastic or composite for the shaft. The evolution of the entire piece of arrow had changed so much, etc from the head

HAMPTON MACHINE TOOL COMPANY On September 14, 2007, Jerry Eckwood, vice president of the Wellington National Bank was considering a loan request from a customer also located in Wellington, New Zealand. The company, Hampton Machine Tool Company, had requested renewal of an existing $1 million loan originally to be repaid September 30, 2007. In addition to the renewal of the existing loan, Hampton was asking for an additional load of $350,000 for planned equipment purchases in October. Under

transitions related in glass formation. At transition point’s temperature Tg, a laser light is applied to heat polymer materials. Using pressure as a constant variable and temperature as a changing variable it is possible to model the glass transition state. He used some mathematical models that he had tested on glass transition dynamics. In his lab more than seventy materials were identified or verified using thermodynamical scaling models. Moreover he talked about how Lenard Jones potential plot

Recovery, Recrystallization and Grain Growth Objective To study the effects of cold working on the microstructure and mechanical properties of 70/30 Cartridge Brass. Background A small percentage of the energy expended in plastically deforming a material remains stored in the metal as an increase in internal energy. Changes are produced in both its physical and mechanical properties. Principally, there is a marked increase in hardness and electrical resistivity with the amount of cold working. Microstructurally

UNDER SURFACEACTIVE SUBSTANCES (1) The main objective of this work was to develop the influence of surface-active substances in the mechanical properties of injected plastic parts in presence of cracks, a tension test and a constant load. The material used was Polystyrene and the surface-active substances were olive oil and corporal sweat. This study was conducted because it was observed that the surface-active substances affects the mechanical properties of the resin as well as the presence of
