[Please Write Clean and Provide Complete Explanation] One end of a 2 m long steel rod (d = 3 cm) is rigidly attached to a wall so that the rod is perpendicular to the wall. The other end of the rod is welded to a second rod, which is 1 m long (d = 1.0 cm). The second rod is parallel to the wall and the floor. A vertical force of 50 N is applied to the end of the second rod. For both rods, the modulus of elasticity is 210 × 109 Pa and the shear modulus is 79 × 10 9 Pa. There is an infinitesimally small cubic element at the top surface of the 3 cm diameter rod immediately adjacent to the wall, that is, at (0, 1.5, 0). What is most nearly the maximum normal stress due to the bending moment?
