A vertical single cylinder engine has a cylinder diameter of 250 mm and stroke length of 450 mm. The reciprocating parts have a mass of 180 kg. The connecting rod is four times the crank radius and the speed is 360 r.p.m. when the crank has turned through an angle of 45° from top dead centre, the net pressure on the piston is 1.05 MN/m². Calculate the effective turning moment on the crankshaft for this position.

For the single slider crank mechanism shown in figure 1, the crank OBhas a constant clockwise angular velocity of 2000 rpm. For the crankposition indicated, determine (a) the angular velocity of the connectingrod BD, and (b) the velocity of the piston P (c) the angular accelerationof the connecting rod BD and the acceleration of point D (The Piston)
