Question 4

The frictional force between objects that are stationary is called:

Question 5

Couple acting on a body can be;

Question 6

A nail of mass 0.015 kg is driven into a fixed wooden block, Its initial speed is 25 m/s and it is brought to rest in 6 milliseconds. find the value of the force

Question 7

A body initially at rest accelerates uniformly to 1000 rpm in 30 sec. The angular acceleration of the body will be

Question 8

The maximum frictional force, which comes into play, when a body just begins to slide over the surface of the other body, is known as

Question 9

Passenger carts being pulled by a locomotive. So that it tends to move forward. The force is applied along the line of action, the force is a;

Question 10

Mass M slides in a frictionless slot in the horizontal direction and the bob of mass m is hinged to mass M at C, through a rigid massless rod. This system is released from rest with θ =30 °. At the instant when θ = 0, the velocities of m and M can be determined using the fact that, for the system (i.e., m and M together),
