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

Theory of Machine In the below figure, PC is the connecting rod and OC is the crank making an angle θ with the line of stroke PO and rotates with uniform angular velocity at ω rad/s. The Klien's acceleration diagram for determining the acceleration of the piston P is shown by quadrilateral CQNO. The acceleration of the piston P with respect to the crank-pin C is given by ω² × CN ω² × NO ω² × QN ω² × CO ω² × CN ω² × NO ω² × QN ω² × CO ANSWER DOWNLOAD EXAMIANS APP
