Theory of Machine The effort of a Porter governor is equal to (where c = Percentage increase in speed, m = Mass of ball, and M = Mass on the sleeve) c/(m + M) g c/(m - M) g c (m - M) g c (m + M) g c/(m + M) g c/(m - M) g c (m - M) g c (m + M) g 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 remain same Could change or remain unaltered depending on which link is fixed Will not occur Will change Will remain same Could change or remain unaltered depending on which link is fixed Will not occur Will change ANSWER DOWNLOAD EXAMIANS APP
