1. The yielding of a critical fibre of cross-section is a measure to estimate the capacity of a structure in elastic condition.
2. The section naturally resists more design action such as bending/axial force / shear.
3. Uncertainties in estimation of load, imperfection in materials, imperfection in geometry members, effect of residual stress, etc..,are considered in one factors therefore the factor of safety in WSM.
