P5-2

Ignoring the hydraulic cylinder that drives the mechanism, the dump truck bed is a 4-bar linkage of links l12, l23, l34, and l41 as shown on the lower figure. At the position shown the angle between l14 and l34 is 37 degrees. At this position, determine the angular velocity of the truck bed (l34) if the angular velocity of link l12 is 0.deltadeltadeltadelta rad/s. Assume l14 is horizontal.
