Which of the following statements is incorrect for bending of a straight member? O Bending stress is inversely proportional to the moment of inertia of the beam section Bending stress is proportional to the bending moment of the section. Bending stress of a point is proportional to its distance from the neutral axis of the section Bending stress is not a function of the moment of inertia of the beam section

The moment acting on the cross section of the beam is M = 3 kip.ft. (Figure 1) Figure 1.5 in 12 in. 1.5 in.
