Kinetic analysis has to be performed to design the shape and thickness of the links, the joints and to determine the required input torque/force and the resulting output torque/force.
A rigid link acted on by two forces is in static equilibrium only if the two forces are collinear and have the same magnitude in opposite direction
Force Analysis – Static Equilibrium
Three force members – only three forces act on a link. Either three joint forces, or two joint forces and an external or inertia or gravitational force.
The link is in static equilibrium only if the force-vectors add up to zero and they pass through the same point (summation of moment about that point is zero).
