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 Perpendicular to each other Inclined at 45° Opposite to each other Parallel to each other Perpendicular to each other Inclined at 45° Opposite to each other Parallel 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 Could change or remain unaltered depending on which link is fixed Will change Will remain same Will not occur Could change or remain unaltered depending on which link is fixed Will change Will remain same Will not occur 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) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h (S₁ + S₂) / h (S₁ + S₂) / 2h (S₁ - S₂) / 2h (S₁ - S₂) / h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In vibration isolation system, if ω/ωn < 2, then for all values of damping factor, the transmissibility will be (where ω = Angular speed of the system, ωn = Natural frequency of vibration of the system) Equal to unity Less than unity Zero Greater than unity Equal to unity Less than unity Zero Greater than unity ANSWER DOWNLOAD EXAMIANS APP
