Theory of Machine The periodic time is given by (where ω = Angular velocity of the particle in rad/s) ω × 2π 2π/ω π/ω ω/2π ω × 2π 2π/ω π/ω ω/2π 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 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 Will remain same ANSWER DOWNLOAD EXAMIANS APP
