3. You are considering using the material in Problem 2 to construct a 15-ft tall column.
a. Suppose the column must carry a load of 800,000 lb without yielding, and
the maximum allowable deflection at this load is 3 in. What cross-sectional
area is required to meet both requirements? (Use the yield stress defined at
2% strain).
b. Using the cross-sectional area determined in a, determine the maximum
force the column can carry (post-yield), and the maximum deformation the
column can withstand.
