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. Can Stock Photo Inc./corepics Cross Section (a) Can Stock Photo Inc./scanrail A Side View A 18,500 psi 16500 psi (b) 3800 psi
