Question

state two conditions for a body acted upon by several forces to be in equilibrium

Answer 1

When a body is moving at a constant velocity in a straight line or is not moving it is said to be in equilibrium. If a body is not moving it is said to be in static equilibrium. A body does not move when the forces acting on it cancel each other.

Two conditions necessary for a body to be in equilibrium are:

1. The sum of rotational forces or moments should be zero.

2. The vector sum of all external forces should be zero.

Answer 2

Answer:

1.all the translational forces should be zero.

2.all the clockwise moments should be equal to all the anticlockwise moments.
