Beam Analysis Using a Spreadsheet
Use the spreadsheet you developed for HW #8 to analyze the beams below. For each beam:
1. Analyze the beam using your spreadsheet. Print a copy of the spreadsheet input and
output.
2. Draw the deflected shape of the beam. Indicate the magnitude of all displacements
(deflections and rotations).
3. Draw an exploded free body diagram of the beam showing the member end forces.
Also draw the shear and moment diagrams.
