SOLVED:The length of the beam in Figure 4.18 of Sample Problem 4.2 is L=200  mm. The maximum transverse shear stress is 32.61 MPa, and the maximum bending stress is 86.96 MPa. What length, L, is required to produce a maximum bending stress in the beam, to equal the magnitude of the maximum shear stress of 32.61 MPa ? The cross-sectional geometry of the beam remains the same as in Figure 4.18.
