Question

question 4
what is the name of a graphical representation of the bending moment equation along the span of the beam?
free body diagram
space diagram
bending moment diagram
shear diagram

Explanation:

A bending - moment diagram shows the variation of bending moment along the length (span) of a beam. A free - body diagram shows all the forces acting on a body. A space diagram is a general representation of the structure in space. A shear diagram shows the variation of shear force along the beam.

Answer:

C. bending moment diagram
