Theory of Machine The displacement of a flat faced follower when it has contact with the flank of a circular arc cam, is given by (where R = Radius of flank, r₁ = Minimum radius of the cam, and θ = Angle turned through by the cam) (R - r₁) (1 - cosθ) R (1 - sinθ) R (1 - cosθ) (R - r₁) (1 - sinθ) (R - r₁) (1 - cosθ) R (1 - sinθ) R (1 - cosθ) (R - r₁) (1 - sinθ) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A typewriter mechanism has 7 numbers of binary joints, six links and none of higher pairs. The mechanism is Kinematically sound Data is not sufficient to determine same Not sound Soundness would depend upon which link is kept fixed Kinematically sound Data is not sufficient to determine same Not sound Soundness would depend upon which link is kept fixed ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Sensitiveness of the governor is defined as the ratio of the Mean speed to the minimum equilibrium speed Difference of the maximum and minimum equilibrium speeds to the mean speed Mean speed to the maximum equilibrium speed Sum of the maximum and minimum equilibrium speeds to the mean speed Mean speed to the minimum equilibrium speed Difference of the maximum and minimum equilibrium speeds to the mean speed Mean speed to the maximum equilibrium speed Sum of the maximum and minimum equilibrium speeds to the mean speed ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will remain same Will change Could change or remain unaltered depending on which link is fixed Will not occur Will remain same Will change Could change or remain unaltered depending on which link is fixed Will not occur ANSWER DOWNLOAD EXAMIANS APP
