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 Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation between number of links (l) and number of joints (j) in a kinematic chain is l = (3/4).(j + 3) l = (2/3).(j + 2) l = j + 4 l = (1/2).(j + 2) l = (3/4).(j + 3) l = (2/3).(j + 2) l = j + 4 l = (1/2).(j + 2) ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2.22 mm 2.50 mm 3.0 mm 2 mm 2.22 mm 2.50 mm 3.0 mm 2 mm ANSWER DOWNLOAD EXAMIANS APP
