In the figure shown, forces of equal magnitude are applied to the two ends of a uniform rod. Consider A as the cross sectional area of the rod. For this situation, mark out the incorrect statements.

All of the statements are factual statements. Stress is defined as internal force developed in the system per unit cross-sectional area and is not defined as force applied per unit cross-section area, although in equilibrium, stress is numerically equal to applied force per unit area.
