Figure P11-3 shows a fourbar linkage and its dimensions. The steel crank and rocker have uniform cross sections 1 in wide by 0.5 in thick. The aluminum coupler is 0.75 in thick. In the instantaneous position shown, the crank O2A has ω = 40 rad/sec and a = -20 rad/sec2. There is a horizontal force at P of F= 50 lb. Find all pin forces and the torque needed to drive the crank at this instant.
