Sometimes when drawing

shean and moment diagrams live
we will see V=0 at a location that is not obvious. We
need to know this, location to draw a moment diagram.

Transcribed Image Text:For the beams below, draw the shear and moment diagrams and list the max shear and max bending moment for each:
Some may have the shear diagram hit zero at an unknown distance (not obviously at the middle). In those cases, use this
example to find the exact location in the beam where V = 0.
