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 and velocity of the piston P is maximum Acceleration and velocity of the piston P is zero Acceleration of the piston P is maximum and its velocity is zero Acceleration of the piston P is zero and its velocity is maximum Acceleration and velocity of the piston P is maximum Acceleration and velocity of the piston P is zero Acceleration of the piston P is maximum and its velocity is zero ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the addenda on pinion and wheel is such that the path of approach and path of recess are half of their maximum possible values, then the length of the path of contact is given by (where r = Pitch circle radius of pinion, R = Pitch circle radius of wheel, and φ = Pressure angle) [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 [(r² + R²) sinφ]/2 ANSWER DOWNLOAD EXAMIANS APP
