Mechanism With Higher Pair Basic definitions - Machines is a device which is used to accomplish work. Mechanism is the mechanical portion of a machine that has the function of transferring motion and forces to an output whit the help of a power source. Mechanisms are collection of rigid members or links connected by joints. In other words, if several bodies are grouped in such a way that the motion of one cause constrained and predictable motion to the others, it is known as mechanism. Rigid and Resistant bodies- If a body undergoes the action of forces and it does not suffer any distortion, it is said to be a rigid body. Resistant bodies are those which are rigid for a cause. For example, in a case of hydraulic press, fluids can also act as resistant bodies when they are compressed. Links - A resistant body or group of resistant bodies connecting each other and preventing their relative motion is called as a link. It can be also defined as a mem...
