Question

Please show ALL work and answer ALL parts

In the engine system shown -250 mm and b 100 mm. The connecting rod BD is assumed to be a 1.2-kg uniform slender rod and is attached to the 1.8-kg piston P. The AB rod is rotating counterclockwise at a constant angular velocity of 15 rads/s. Determine all the reactionary forces as a function of θ and plot these forces as a function of θ. At what angle(s) is the reaction force at point D a maximum? Also, plot the accelerations of the points B and D. The rod AB has a mass of 0.2 kg. Assume no friction.
