1. Which has the larger Area Moment of Inertia, a 2" x 2" square beam of high strength stainless steel or a 2" x 2" square beam of balsa wood? Support your answer qualitatively or quantitatively.
2. Should the Elastic modulus of a beam change if the unsupported length of the beam is changed? Why?
3. What would be the percent change in deflection if a solid rectangular beam has its unsupported length changed from 30 inches to 36 inches? What does this tell you about the importance of unsupported beam length in structural design?
4. Is the Modulus of Elasticity indicative of what the failure load of a beam would be? Why?
