Also, compare this formula with that given in Problem 6.9-11 for the special case of ß = 0 here and a = h/2 in both formulas.arrow_forwardAnswer the following:arrow_forwardDetermine the moment M that should be applied to the beam in order to create a compressive stress at point D of σD = 30 MPa. Also sketch the stress distribution acting over the cross section and calculate the maximum stress in the beam. Construct the stress distribution in 2D similar to in-class examples, rather than isometrically similar to the textbook examples for clarity. Hint: The maximum stress will occur at the extreme fiber (Either top or bottom). For symmetric cross- sections, the extreme fiber for the tensile and compressive stresses will have the same magnitude. A 25 mm M D 150 mm 25 mm 25 mm B 150 mm 25 mmarrow_forward
