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 × CO ω² × QN ω² × NO ω² × CN ω² × CO ω² × QN ω² × NO ω² × CN 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/2 Remain same as before Become equal to R/4 Become equal to 2R Become equal to R/2 Remain same as before Become equal to R/4 Become equal to 2R ANSWER DOWNLOAD EXAMIANS APP
