Theory of Machine The acceleration of a flat-faced follower when it has contact with the flank of a circular arc cam, is given by ω² R cosθ ω² (R - r₁) cosθ ω² (R - r₁) sinθ ω² r₁ sinθ ω² R cosθ ω² (R - r₁) cosθ ω² (R - r₁) sinθ ω² r₁ sinθ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 Become equal to R/4 Become equal to 2R Remain same as before Become equal to R/2 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 Could change or remain unaltered depending on which link is fixed Will not occur Will change Will remain same Could change or remain unaltered depending on which link is fixed Will not occur Will change ANSWER DOWNLOAD EXAMIANS APP
