Question

Consider the diving board configuration shown below, with P = 150 kg Determine the maximum normal stress and maximum shear stress, indicating on your diagram the location of these maximum

stresses, for two possible boards (a) the board is solid rectangular cross-section, 300 mm wide by 35 mm tall (b) the board is a hollow rectangular cross-section with same exterior dimensions as (a) and with a 4 mm wall thickness. Recall: In HW 1, you determined the reaction forces and constructed the shear and moment diagram with a 100 kg person standing at the end, and you also determined the maximum moment and maximum shear.
