Theory of Machine A motor car moving at a certain speed takes a left turn in a curved path. If the engine rotates in the same direction as that of wheels, men due to centrifugal force The reaction on the outer wheels increases and on the inner wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on the outer wheels increases and on the inner wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on the front wheels increases and on the rear wheels decreases 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 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 Become equal to R/4 ANSWER DOWNLOAD EXAMIANS APP
