Theory of Machine The acceleration of a particle at any instant has two components i.e. radial component and tangential component. These two components will be Opposite to each other Inclined at 45° Parallel to each other Perpendicular to each other Opposite to each other Inclined at 45° Parallel to each other Perpendicular to each other 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 Will change Will not occur 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a Hartnell governor, the stiffness of the spring is given by (where S1 and S2 = Spring forces exerted on the sleeve at max. and min. radii of rotation, and h = Compression of the spring) (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ - S₂) / 2h (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / h (S₁ - S₂) / 2h (S₁ + S₂) / h ANSWER DOWNLOAD EXAMIANS APP
