In the engine system shown l = 10 in. and b = 4 in. The connecting rod BD is assumed to be a 3-lb uniform slender rod and is attached to the 4.5-lb piston P. During a test of the system, crank AB is made to rotate with a constant angular velocity of 600 rpm clockwise with no force applied to the face of the piston. Determine the forces exerted on the connecting rod at B and D when θ = 180°. (Neglect the effect of the weight of the rod.)
