Shear force and bending moment diagram problems and solutions pdf

The ability to draw shear force and bending moment diagrams on beam-like components is an important skill for mechanical engineering students. We found that some students had difficulty to draw effectively the shear force and bending moment diagrams during the course and even in their senior year.

The bending moment diagrams for concentrated forces are linear; that is, they have constant slope (they are of the form y = mx+c where m is the slope). These are most easily derived from the area under the shear force diagram. The area under the shear force diagram to the left of x = 0 is 0 so the point (0,0) is on the bending moment diagram.
