An instantaneous configuration of a four-bar mechanism, whose plane is horizontal, is shown in the figure below. At this instant, the angular velocity and angular acceleration of link O2A are ω = 8 rad/s and α = 0, respectively, and the driving torque (τ) is zero. The link O2A is balanced so that its centre of mass falls at O2.

By finding AB we get,
the sum of small link+longest link< other="" two="" />
adjacent link link crank is hinged then we get crank -rocker mechanism
