TRUE OR FALSE ONLY. PLEASE HELP 1. Area of shear diagram is equal to the magnitude of bending moment. A 2. Parallel area is the resisting area for shear force. 3. The deflection of the beam is its elastic curve when the beam bends 4. Flexural stress is a bending stress. 5. The elastic limit is the limit beyond which the material will no longer go back to its original shape when the load is removed, or it is the maximum stress that may be developed such that there is no permanent or residual deformation when the load is entirely removed.
