Problem 2. Determine expressions for the shear force V(x) and the bending moment M(x) inside beam AD, each as a function of the location x along the beam's length, where x = 0 is defined as the location of the cantilever support at A. Note that there is a concentrated external moment applied at point B. Express V(x) and M(x) a piecewise functions. Then sketch diagrams for V(x) and M(x), labeling the magnitudes of key features on the diagram. 225 in.lbf B 25 lbf 12in 15in 12in 75 lbf D
