Figure 2-3a shows an inclined plane, AB is the base, BC is the height and AC the inclined plane. A machine (or mechanical device) is a mechanical structure that uses power to apply forces and control movement to perform an intended action. In this chapter, we shall study the mechanisms of the various parts or bodies from which the machine is assembled. Explore journal content Latest issue Articles in press Article collections All issues. Power is produced by the engine which makes use of a mechanism called slider crank mechanism. No public clipboards found for this slide. For example The slider-crank chain (Engine Mechanism) becomes an oscillating-cylinder mechanism if the original "connecting-rod" is fixed, or a Whitworth "Quick-return mechanism" if the crank becomes the fixed link.
