Unformatted text preview: Strength of Materials: Lecture 2 1-Axial Force, Shear Force, and Bending Moment Diagrams: The three components of moment which can occur at a section of a member act around the three coordinate axes Fig. (c). The positive sense of the force components on the cut section viewed toward the origin coincides with the positive direction of the coordinate axes as shown in Fig. (b). The quantities shown in Fig.(c) will be represented alternatively by double headed vectors as in fig. (d). The sense of these vectors follows the right- hand screw rule. *M x is the torque = T For planar problems the notation for and the diagrammatic representation of the forces components are shown in Fig. (e and f). Side view of forces acts on the body; P (axial force), V (shear force), and the M (moment). 7 From the drawing shown before (P = F): F x : Axial Force σ (normal or direct stress) = A P--- (1) F y , F z : Shear Force τ (shear force) = It VQ--- (2) M x : Twisting Moment or Torsion T = J R .
