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 × CN ω² × QN ω² × NO ω² × CO ω² × CN ω² × QN ω² × NO ω² × CO ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation between number of pairs (p) forming a kinematic chain and the number of links (l) is l = 2p - 3 l = 2p - 4 l = 2p - 2 l = 2p - 5 l = 2p - 3 l = 2p - 4 l = 2p - 2 l = 2p - 5 ANSWER DOWNLOAD EXAMIANS APP
