Problem $2.$ For the beam shown below, consider the cross section of Problem $1(24-$inch wide and $36$inch deep$),$ reinforced per la$($iii$)($i$.$e$.,$ strain hardening in the longitudinal reinforcement with transverse reinforcement sets at $4$ inches on center$).$ Assume the beam is massless and the longitudinal reinforcement is fully developed. Estimate the maximum possible applied load P at the mid$-$span. Estimate

the corresponding displacement at the mid$-$span of the beam using first principles as discussed in the class and identify your assumptions. Use the XTRACT results, if useful.
