Table Figures Figure 1 pnumatics Introduction The use of mechanisms that utilize compressed air or gases such as nitrogen when piped to be able to allow the transmission of force and energy is called Pneumatics (Woodford, 2018). The science as well as the technology of pneumatics has been in use for thousands of years; for […]

A free body diagram consists primarily of a sketch of the body in question and arrows representing the forces applied to it. The selection of the body to sketch may be the first important decision in the problem solving process. For example, to find the forces on the pivot joint of a simple pair of pliers, […]

The propulsion system for an aircraft generates the mechanical power for the movement. Lightweight piston engines or gas turbines are aircraft engines. A size of an airplane engine relates to its efficiency. The various types of engines function similarly. FUNCTION OF THE […]

This review will use two major studies amongst others, one by Wan Peng from the Dalhousie University and the other by Mark Estabrook at MediaTek. These have been undertaken to determine the effectiveness […]

HOOKE’S LAW: Hooke’s lawof elasticity is an approximation that states that the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit. Materials for which Hooke’s law is a useful approximation are known as linear elasticor “Hookean” materials. Get Help […]

Introduction: A spare wheel well, also called spare wheel baffle, is a recessed storage tub located in the trunk of the vehicle. As the name suggests, it houses the spare wheel and tyre, along with the lug wrench and wheel jack. Traditionally, it was made of stamped steel. [1] However, since this part has an […]
