Theory of Machine 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 CQNO. The acceleration of the piston P with respect to the crank-pin C is given by ω² × QN ω² × CN ω² × NO ω² × CO ω² × QN ω² × CN ω² × NO ω² × CO ANSWER DOWNLOAD EXAMIANS APP
