Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ - ω₂)r (ω₁ + ω₂)r (ω₁ - ω₂)2r ω₁.ω₂.r (ω₁ - ω₂)r (ω₁ + ω₂)r 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) (r₁ + r₂) [(1 - cosθ)/cosθ] (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) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of ascent of cam is defined as the angle Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower ANSWER DOWNLOAD EXAMIANS APP
