1. Answer the question with True or False. a. When a beam or frame is subjected to transverse loadings, the three possible internal forces that are developed are the normal force, shear force, and the bending moment. (TRUE/FALSE) b. The normal force at any section of a structure is defined as the algebraic sum of the axial forces acting on either side of the section (TRUE/FALSE) c. Shear and moment diagrams for a beam provide graphical descriptions of how the internal shear and moment vary throughout the beam’s length. (TRUE/FALSE) d. Normal force is represented by ‘N’. Shear force, the vertical force is represented with ‘M’. Bending moment is ‘V’. (TRUE/FALSE) e. When a structure is not moving, the resultant of all the applied forces must be equal to zero. (TRUE/FALSE) f. In a 3D case, a bending moment has a negative sign when it's creating concave upward rotation on the section. (TRUE/FALSE)
