If a body is acted upon by a number of coplanar non-concurrent forces, if any

22) A smooth cylinder lying on its convex surface remains in ______ equilibrium.

Answer is:

unstable

Explanation:

A smooth cylinder lying on its convex surface remains in unstable equilibrium.

23) Three forces acting on a rigid body are represented in magnitude, direction and line of action by the three sides of a triangle taken in order. The forces are equivalent to a couple whose moment is equal to

Answer is:

twice the area of the triangle

Explanation:

Three forces acting on a rigid body are represented in magnitude, direction and line of action by the three sides of a triangle taken in order. The forces are equivalent to a couple whose moment is equal to twice the area of the triangle.

24) The principle of transmissibility of forces states that, when a force acts upon a body, its effect is

same at every point on its line of action

different at different points on its line of action

minimum, if it acts at the centre of gravity of the body

maximum, if it acts at the centre of gravity of the body

Answer is:

minimum, if it acts at the centre of gravity of the body

Explanation:

The principle of transmissibility of forces states that, when a force acts upon a body, its effect is minimum, if it acts at the centre of gravity of the body.

25) A smooth cylinder lying on a ______ is in neutral equilibrium

Answer is:

horizontal surface

Explanation:

A smooth cylinder lying on a horizontal surface is in neutral equilibrium
