Question
nc./Johan H σy 7.2-1 The stresses on the bottom surface of a fuel tanker (figure part a) are known to be o = 7750 psi, = 1175 psi, and 7 xy = 940 psi (figure part b). Determine the stresses acting on an element oriented at an angle = 55° from the x axis, where the angle is positive when counterclockwise. Show these stresses on a sketch of an element oriented at the angle 0. (a) PROBLEM 7.2-1 (b) 1175 psi Ţ 940 psi 7750 psi 7.2-5 The stresses acting on element A on the web of a train rail (see figure part a) are found to be 6500 psi tension in the horizontal direction and 18,500 psi com- pression in the vertical direction (see figure part b). Also, shear stresses with a magnitude of 3800 psi act in the directions shown. Determine the stresses acting on an element ori- ented at a counterclockwise angle of 30° from the horizontal. Show these stresses on a sketch of an ele- ment oriented at this angle. Cross Section (a) PROBLEM 7.2-5 B A Side View A (b) 18,500 psi 76500 psi 3800 psi
