Static and Dynamic Force Analysis:

In a mechanism, the members are subjected to some form of loading. These loads might be due combustion of hydraulic pressure in turbines or fuel in IC engines, friction force because of sliding and turning pairs, weight, inertia forces,  etc. Some forces are not always constant for different configurations of machine however these forces also might be considered constant for a specific configuration. The applied forces modify with the change in configuration and, so, the loads carried by different members also change. Hence, each of configurations of the machine is considered as system of rigid bodies in equilibrium.

Objectives

• perform static force analysis of a mechanism,
• form dynamically corresponding system of two point masses for a specified link,
• resolve friction circles and friction axis, and
• carry out dynamic force analysis.
