43 draw the shear diagram for the beam.
The value of the shear just to the right of. C. C C can be found by sectioning the beam at this point. This yields the free-body diagram shown in equilibrium in Fig. 4-13e. This point. ( V = − 5 0 0 l b) (V=-500 \mathrm {lb}) (V = −500 lb) is plotted on the shear diagram. As before, w = 0. The areas of the shear force diagram for the different segments of the beam are shown in Fig. (c). We begin by noting that M_{A} = 0 because no couple is applied at A. Plot point i. Proceeding from left to right across the beam, we construct the bending moment diagram as follows: M_{B}=M_{A} +area of V-diagram] _{A}^{B} = 0 + (−800) = −800 ... (c) on a drawing of the beam sketch the inclined cracks that would develop at a, b, and c. Draw the shear diagram for the beam. 6.30. (b) show the direction of the principal tensile stresses at middepth at points a, b, and c. Draw the stress strain graph of an ms rod and mark its main points. Draw the shear diagram for the beam.
