1. If all the reactive forces are intersecting at the common point or pass through a common axis when _____________

The body is in equilibrium

The body is in deformation

The body is said to be achieve stability but no equilibrium

The body is said to be improperly constrained

2. To satisfy the conditions of the equilibrium, the must not only be having a net force zero, but also be properly held or constrained on its supports.

False

True

3. If the non-Uniform loading is of the type of parabola then?

The net load will not be formed as all the forces will be cancelled

The net force will act at the centroid of the parabola

The net force will act the centre of the parabola
