Theory of Machine The relation between number of links (l) and number of joints (j) in a kinematic chain is l = (2/3).(j + 2) l = (1/2).(j + 2) l = (3/4).(j + 3) l = j + 4 l = (2/3).(j + 2) l = (1/2).(j + 2) l = (3/4).(j + 3) l = j + 4 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will change Could change or remain unaltered depending on which link is fixed Will remain same Will not occur Will change Could change or remain unaltered depending on which link is fixed Will remain same Will not occur ANSWER DOWNLOAD EXAMIANS APP
