A beam of length L is loaded in the xy-plane by a uniformly distributed load, and by a concentrated tip load parallel to the z-axis, as shown in the figure. The resulting bending moment distribution about the y and the z axes are denoted by M, and M., respectively. Which one of the options given depict qualitatively CORRECT variation of My and Mz along the length of the beam? (A) M, 0 L x M. 0 x L 9 (B) P M 0 M. x 0 x L L
