Getting lost in my math

2. A moment is applied to a cantilevered beam shown below (left). The cross section is shown below (right). The allowable stresses for the material are 120 MPa in tension and 150 MPa in compression. Determine the largest allowable moment, M, that can be applied. (Hint: must check both conditions.) (Intermediate Ans: ybar = 55.04 mm; you must show these calculations in your HW.) Ans: M = 7.67 kN-m 48 Z mm C M Fixed_S 36 to wall mm 12 mm 6 6 mm 36 mm
