Which of the following statements is incorrect for bending of a straight member? 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 Bending stress is proportional to the bending moment of the section. Bending stress is inversely proportional to the moment of inertia of the beam section

Given data: Bending stress concept.Simple bending equation: MI=fy=ER where, M is moment I is moment of inertia f is bending stress y is the distance from neutral axis E is modulus of elasticity R is radius of curvature.Bending stress: f=MIy From this we can say that, 1) f∞y 2) f∞1I 3) f∞M The second statement is incorrect: Bending stress is not a function of the moment of inertia of the beam section.Answer: Incorrect statement "Bending stress is not a function of the moment of inertia of the beam section"

Answered: Which of the following statements is…

to the direction of loading. When When solving for Normal/Axial/Compressive/Tensile Stress we look at an area of our member that is solving for basic Shear Stress we look at an area to the direction of loading. This is because of how the members will fail in either situation and what resists that failure. Parallel, Parallel 1000 Parallel, Perpendicular Perpendicular, Parallel Perpendicular, Perpendicular
