- On a mass ‘m’ describing a circular path of radius ‘r’, the centrifugal force
- The condition of equilibrium for any system of forces in a plane is
- The force acting on a point on the surface of a rigid body may be considered to act
-
A 2 m long ladder rests against a wall and makes an angle of 30° with the horizontal floor. Where will be the instantaneous center of rotation when the ladder starts slipping ?
i. 1.0 in from the wall
ii. 1.732 m from the wall
iii. 1.0 m above the floor
iv. 1.732 m above the floor
The correct answer is -
If a body is lying on a plane whose inclination with the horizontal is less than the angle of friction, then
i. a force is required to move the body upwards
ii. a force is required to move the body downward
iii. the body will not be in equilibrium
The correct answer is -
The torque produced by a force depends on
i. the magnitude of the force
ii. the direction of the force
iii. the point of application of the force relative to origin
The correct answer is - Select the correct statement
- The resultant of two forces P and Q is R. If Q is doubled, the new resultant is perpendicular to P. Then,
- Power developed by a torque, is
- The shape of a suspended cable for a uniformly distributed load over it is
