Theory of Machine The relation between number of links (l) and number of joints (j) in a kinematic chain is l = (1/2).(j + 2) l = j + 4 l = (2/3).(j + 2) l = (3/4).(j + 3) l = (1/2).(j + 2) l = j + 4 l = (2/3).(j + 2) l = (3/4).(j + 3) 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 × NO ω² × QN ω² × CN ω² × CO ω² × NO ω² × QN ω² × CN ω² × CO ANSWER DOWNLOAD EXAMIANS APP
