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 and velocity of the piston P is maximum 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 zero Acceleration and velocity of the piston P is maximum 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 zero ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r₁ = Minimum radius of the cam, r₂ = Radius of the roller follower, and θ = Angle turned by the cam from the beginning of the follower displacement) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ + r₂) (1 + cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ + r₂) (1 + cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] ANSWER DOWNLOAD EXAMIANS APP
