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. The distance between fixed pivots of crank and followers is 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 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)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) (1 + cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) ANSWER DOWNLOAD EXAMIANS APP
