Theory of Machine In a Hartnell governor, if a spring of greater stiffness is used, then the governor will be More sensitive Less sensitive Unaffected of sensitivity Isochronous More sensitive Less sensitive Unaffected of sensitivity Isochronous 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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a left turn.
