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 = 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 n = 2(l - 1) - 2j ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 2(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 3(l - 1) - 2j - h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A machine mounted on a single coil spring has a period of free vibration of tp . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system will become tp /4 16 tp tp /16 4 tp tp /4 16 tp tp /16 4 tp ANSWER DOWNLOAD EXAMIANS APP
