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
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 anticlockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ + ω₂) r (ω₁ - ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ + ω₂) r ANSWER DOWNLOAD EXAMIANS APP
