Resolution of a force:
Sol.: When a force is resolved into two parts along the two mutually perpendicular directions, without changing the effects of it on the body, the parts along those directions are called as resolved parts. And process is called as resolution of a force.
Horizontal Component ( ∑ H) = Psin θ
Vertical Component ( ∑ V) = Pcos θ
Principle of Resolution: It states that the algebraic sum of the resolved parts of a number of forces in a given direction is equal to resolved part of their resultant in same direction.
Types of stresses: In general stress is divided in to three group as: various types of stresses may be classified as: 1. Simple or direct stress (Tension, Compressi
