Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁=0.55 in and the connecting rod (member BC) has a length of r2 = 4.25 in. The crankshaft rotates in the counterclockwise or positive direction.
