Strength of Materials1 Strength of Materials Strength of Materials 목차 Stress & Strain When a force is applied to a structural member, that member will develop both stress and strain as a result of the force. Stress is the force carried by the member per unit area, and typical units are lbf/in2 (psi) for US Customary units and N/m2 (Pa) for SI units: where F is the applied force and A is the cross-sectional area over which the force acts.
