**Exercise 38** Section 7.2 (Lesson 14) MecMovies M9.1**Given:** A beam with a rectangular cross section is simply supported and loaded at its center with a force \(P\). The dimensions \(b\), \(h\), and \(L\) are shown in the figure.**Find:** Determine (a) the maximum bending stress \(\sigma_{\text{max}}\) and (b) the maximum shear stress \(\tau_{\text{max}}\) in this beam. (c) Then obtain the ratio \(\tau_{\text{max}}/\sigma_{\text{max}}\). *Hint: The maximum stresses occur at different locations in the beam. Be sure to show sufficient work to justify your answers.***Answers:** (a) \(\frac{3PL}{2bh^2}\) (b) \(\frac{3P}{4bh}\) (c) \(\frac{h}{2L}\)**Diagram Explanation:**The figure alongside illustrates a beam with a rectangular cross section. The beam is simply supported at both ends and loaded at the center by a force \(P\). The dimensions of the beam are denoted as: - \(b\): Width of the beam - \(h\): Height of the beam - \(L\): Length of the beamThese dimensions are crucial for calculating the stresses experienced by the beam under the applied force.
