The box beam shown in Figure P8.63b has dimensions of b = 80 mm, d = 120 mm, and t = 8 mm. A downward concentrated load of P = 42 kN acts on wall BC of the box at a distance of a = 35 mm below the z centroidal axis as shown in Figure P8.63a. Determine the normal stress: (a) at corner A. (Ans. to check: 22.9 Mpa (T)) (b) at corner D. (Ans. to check: 9.01 Mpa (C))
