If the beam is $12 \mathrm{ft}$ long, $W$ has mean 1.5 and standard deviation $.25,$ and the fixed loads are as described in part (a) of Exercise $66,$ what are the expected value and variance of the bending moment? [Hint: If the load due to the beam were $w$ kip-ft, the contribution to the bending moment would be $\left.w_{0}^{12} x d x .\right]$
