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.
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.
