The acceleration diagram gives you the acceleration of the various bits. You also have the masses. The rest is trig. For example, the piston is accelerating in a straight line. Because the connecting rod is at an angle to the direction of piston travel there is a force component perpendicular to the direction of piston travel and another along the direction of piston travel. Those forces act on A in the direction along the connecting rod.
