Question

In plotting the curves for Shear force diagrams and bending moment diagrams, what is plotted on the common axis?

• A. Mass of the section
• B. Orienta tion of the section's normal force
• C. Positior of the section
• D. Elasticity of the section

Answer 1

Answer:

C. Positior of the section

Shear force and bending moment diagrams plot position of the section on the abscissa and shear force/bending moment on the ordinate. Shear force is the force trying to shear off the section, obtained by summing vertical forces. Bending moment is the moment trying to bend the section, obtained by summing all moments. Shear force diagram shows shear force and bending moment diagram shows bending moment.
