Q1:

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)

A (r1 - r2)(1 - cosθ)

B (r1 + r2)(1 + cos θ)

C (r1 - r2)

D (r1 + r2)

ANS:D - (r1 + r2)
