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) (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] ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler.
