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 a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h ANSWER DOWNLOAD EXAMIANS APP
