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, if N coincides with O, then Acceleration of the piston P is zero and its velocity is maximum Acceleration of the piston P is maximum and its velocity is zero Acceleration and velocity of the piston P is zero Acceleration and velocity of the piston P is maximum Acceleration of the piston P is zero and its velocity is maximum Acceleration of the piston P is maximum and its velocity is zero Acceleration and velocity of the piston P is zero Acceleration and velocity of the piston P is maximum ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
