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 Remain same as before Become equal to R/2 Become equal to 2R Become equal to R/4 Remain same as before Become equal to R/2 Become equal to 2R Become equal to R/4 ANSWER DOWNLOAD EXAMIANS APP
