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 2R Become equal to R/4 Become equal to R/2 Remain same as before Become equal to 2R Become equal to R/4 Become equal to R/2 Remain same as before ANSWER DOWNLOAD EXAMIANS APP
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 - r₁) sinθ ω² r₁ sinθ ω² (R - r₁) cosθ ω² R cosθ ω² (R - r₁) sinθ ω² r₁ sinθ ω² (R - r₁) cosθ ω² R cosθ ANSWER DOWNLOAD EXAMIANS APP
