Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The minimum length of the coupler will be 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm 45 mm 95 mm Slightly more than 45 mm Slightly less than 45 mm 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
