Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video. The box beam shown in Figure A has dimensions of b = 83 mm, d = 117 mm, and t = 9 mm. A downward concentrated load of P = 28 kN acts on wall BC of the box at a distance of a = 34 mm below the z centroidal axis as shown in Figure B. Determine the normal stress: (a) at corner A. (b) at corner D. D FIGURE A (a) σ₁A = Z (b) OxD = X i B D b FIGURE B MPa b- MPa P Your answers below must be consistent with the sign convention for normal stresses. B с a d
