Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 2(l - 1) - 2j n = (l -1) - j n = 4(l - 1) - 3j n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = (l -1) - j n = 4(l - 1) - 3j n = 3(l - 1) - 2j 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 × CO ω² × CN ω² × QN ω² × NO ω² × CO ω² × CN ω² × QN ω² × NO ANSWER DOWNLOAD EXAMIANS APP
