Question

If the number of coplanar concurrent forces acting simultaneously on a body, be
represented in magnitude and direction by the sides of a polygon taken in order
then their resultant is represented in magnitude and direction by the closing side
of the polygon taken in opposite order is called
Triangle law of forces
Law of parallelogram of forces
Polygon law of forces
Law of moments

Answer 1

Answer:

When two or more forces act on a body, they are called to form a system of ... cting simultaneously on a particle, be represented in magnitude and ... closing side of the polygon, taken in opposite order.

Answer 2

Explanation:

Equilibrium of Three Forces HTML5

A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply : The lines of action are coplanar (in the same plane) ... The vector sum of these forces is equal to the zero vector.
