Equilibrium conditions:
What are equilibrium conditions for non concurrent force system?
Sol.: For the Equilibrium of non concurrent forces there are three conditions:
1. The sum of all the horizontal forces is equal to zero, that is
H = 0
2. The sum of all the horizontal forces is equal to zero, that is
V = 0
3. Sum of the moment of all the forces about any point is equal to zero, that is
M = 0
If any of the conditions is not fulfilled then the body won't be in equilibrium.
Define equilibrant.
Sol.: The force that brings the set of forces in equilibrium is called as equilibrant. As a matter of fact, the equilibrant is equal to resultant force in the magnitude, but opposite in nature.
Nominal Stress and True Stress: Nominal stress is the ratio of force per initial cross sectional area (original area of cross section). Nominal stress = Force / initial ar
