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 change Will not occur Will remain same Could change or remain unaltered depending on which link is fixed Will change Will not occur ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the crank is at the inner dead center, in a reciprocating steam engine, then the acceleration of the piston will be ω²r. n/(n - 1) ω²r. n/(n + 1) ω²r. (n + 1)/n ω²r. (n - 1)/n ω²r. n/(n - 1) ω²r. n/(n + 1) ω²r. (n + 1)/n ω²r. (n - 1)/n ANSWER DOWNLOAD EXAMIANS APP
