Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) cotφ - cotα = c/b sinφ + sinα = b/c cosφ - sinα = c/b tanφ + cotα = b/c cotφ - cotα = c/b sinφ + sinα = b/c cosφ - sinα = c/b tanφ + cotα = b/c ANSWER DOWNLOAD EXAMIANS APP
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 = (l -1) - j n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = (l -1) - j n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = 4(l - 1) - 3j ANSWER DOWNLOAD EXAMIANS APP
