Theory of machines
1) The unit of linear acceleration is m/s2
2) The angular velocity of a body rotating at N r.p.m is 2πN/60
3) The liner velocity of a body rotating at w rad/s along a circular path of radius r is given by w.r
4) When a particle moved along a straight path, then the particle has tangential acceleration only
5) When a particle moves with a uniform velocity along a circular path,then the particle has centripetal acceleration only
6) The force which acts along the radius of a circle and directed towards the centre of the circle is known as centripetal force
7) The unit of mass moment of inertia in S.I unit is kg-m2
8) Joule is a unit of work
9) The bodies which rebound after impact are called elastic bodies
10) The coefficient of restitution for inelastic bodies is zero
