Let us suppose that a block resting on an inclined plane just begins to slide down the plane when the angle of inclination is gradually increased to 30, the coefficient of friction will be equal to
A body in equilibrium may not have
The maximum value of static friction is called
A body is said to be perfectly elastic if
Which kind of storage device can be carried around?
Which of the following pairs have identical dimensions?
7 A 30 kg. block lies on a frictionless table and is connected to a 10 kg block by a rope passing over a frictionless pulley
The force of friction that comes into action after the motion has started is known as
Let a disc, a cylinder, a solid sphere, and a ring be rolled down in an inclined plane simultaneously. Which will reach first?
Assuming the pulley to be frictionless and mass less, the smallest coefficient of static friction is 0.33 to cause the cylinder to roll. If for the cylinder M=70kg and radius of gyration 400 mm. then
