Theory of machines

In the below figure, PC is the connecting rod and OC is the crank making an angle θ with the line of stroke PO and rotates with uniform angular velocity at ω rad/s. The Klien's acceleration diagram for determining the acceleration of the piston P is shown by quadrilateral C Q NO, if N coincides with O, then

A acceleration and velocity of the piston P is zero

B acceleration and velocity of the piston P is maximum

C acceleration of the piston P is zero and its velocity is maximum

D acceleration of the piston P is maximum and its velocity is zero

ANS:C - acceleration of the piston P is zero and its velocity is maximum
