## Theory of Machine A body having moment of inertia o:m2 is rotating at 210 RPM and r with another body at rest having I 40 kg m2. The resultant speed after ing will be

100 RPM
80 RPM
90 RPM
data are insufficient

## Theory of Machine A point B on a rigid link AB moves with respect to A with angular velocity ω rad/s. The total acceleration of B with respect to A will be equal to

Vector difference of radial component and tangential component
Vector sum of radial component and tangential component
Vector sum of tangential component and Coriolis component
Vector sum of radial component and Coriolis component

Higher pair
Rolling pair
Sliding pair
Lower pair

## Theory of Machine Which of the following statement is correct as regard to the difference between a machine and a structure?

All of these
The parts of a machine move relative to one another, whereas the members of a structure do not move relative to one another
The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only
A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work

## Theory of Machine A single degree of freedom system is given by, m × (d²x/dt²) + c × (dx/dt) + sx = F.cosω.t with usual notations. It represents

Free vibration with damping
Free vibration without damping
Forced vibration with damping
Forced vibration without damping
