the rate of wear and tear is less due to less friction. These are used in aircraft engines and oil engines. C) Four bar linkage system A four bar linkage is the pre-eminent mechanism building block. Four bar linkages are common in aerospace mechanical linkages. At times‚ a mechanism may be a four bar linkage‚ but the fact that a mechanism is a four bar linkage may not be obvious. D) Slotted link mechanism The slotted link mechanism is a mechanism able to transform circular movement into

Alfred Olasiman COE001 / 10:30-11:30 July 21‚ 2014 What is the importance of Civil Engineering? According to my research‚ civil engineering started between 4000 - 2000 BC in Ancient Egypt and Mesopotamia. When humans decided to build their permanent houses‚ the construction of shelter began. Therefore‚ civil engineering considered as one of the oldest field in engineering and is the broadest of the all engineering professions. Civil engineer works to enhance the infrastructures around

decreases. 1b) Steels that contain specified amounts of alloying elements‚ other than carbon and the commonly accepted amounts of manganese‚ copper‚ silicon‚ sulphur and phosphorus are known as alloy steels. Alloying elements are added to change mechanical or physical properties. Alloy steels are melted together in an electric furnace. This step usually involves 8 to 12 hours of intense heat. Next‚ the mixture is cast into one of several shapes including blooms‚ billets and slabs. After various forming

Abstract Philosophy has not paid sufficient attention to engineering. Nevertheless‚ engineering should not use this as an excuse to ignore philosophy. The argument here is that philosophy is important to engineering for at least three reasons. First‚ philosophy is necessary so that engineers may understand and defend themselves against philosophical criticisms. In fact‚ there is a tradition of engineering philosophy that is largely overlooked‚ even by engineers. Second‚ philosophy‚ especially ethics
