What is static force analysis?A four bar mechanism has following dimensions: Length of crank=100 mm, Length of coupler link=450mm, length of rocker-270 mm and length of fixed link=250 mm. A force F=-100i N is applied on to mid-point 'C' of rocker, when crank makes 120 from positive x-axis. Calculate pin forces and torque to be applied on to the crank for equilibrium. 1. A disturbing mass 'm' kg is attached to a shaft. The shaft is rotating at 'n' rpm. radial distance of the center of gravity of the disturbing mass from the axis of rotation is 'r' mm. It is required that the disturbing mass should not be disturbed by any addition or subtraction of mass. Suggest the ways to balance the system and justify by proper expressions. 2. The
