The two equal and opposite forces, whose lines of action are different, form a couple.
A little consideration will show, that a couple does not produce any translatory motion (i.e. motion in a straight line), but a couple produces a motion of rotation of the body on which it acts.
20) Two non-collinear parallel equal forces acting in opposite direction
Answer is:

Answer is:
if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero
Answer is:
mass
Explanation:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass, energy and electric charge.
On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration and velocity.
Answer is:
if three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium
