Only tell using the $4$ given beams that which one will be least weighted????????????

For the following problems, pick the least$-$weight beam; assume the following:

$Fb=24$ksi

$Fv=14\mathrm{.}5$ksi

Defl limit $=\frac{4}{360}$

Use ASD method

$2.$ Beam ${30}^{\text{'}}$ long has concentrated loads of $9$ kips at third points and also a uniformly distributed

$4.$ Beam spanning ${22}^{\text{'}}$ with a concentrated load of $5k{5}^{\text{'}}$ from the left, $12k{13}^{\text{'}}$ from the left and a distributed load of $4\frac{k}{f}t.$
