- The angle which an inclined surface makes with the horizontal when a body placed on it is on the point of moving down, is called
- The resultant of two forces acting at right angles is √34 kg and acting at 60° is 70 kg. The forces are
- The moment of inertia of a circular lamina of diameter ‘d’, about an axis perpendicular to the plane of the lamina and passing through its centre, is
- A circular disc rotates at n rpm. The angular velocity of a circular ring of same mass and radius as the disc and to have the same angular momentum is
- Instantaneous center is at infinity when the angular velocity is
- A disc of mass 4 kg, radius 0.5 m and moment of inertia 3 kg.m² rolls on a horizontal surface so that its center moves with speed 5 m/see. Kinetic energy of the disc is
- A cable loaded with 0.5 tonne per horizontal metre span is stretched between supports in the same horizontal line 400 m apart. If central dip is 20 m, the minimum tension in the cable, will be
- A simple pendulum of length 1 has an energy E when its amplitude is A. If its amplitude is increased to 2A, the energy becomes
- A simple pendulum of length / has an energy E, when its amplitude is A. If the length of pendulum is doubled, the energy will be
- If the horizontal range is 2.5 times the greatest height, the angle of projection of the projectile, is
