Steps for

$2\mathrm{.}1$ Based on the force polygon for this problem$(1\mathrm{.}1),$ which element of the tensile structure carries the highest load? Using steel with an

allowable stress of $30$ ksi $,$ what is the minimum required cross$-$sectional area? $($Recall that stress is force$/$area$.)$

$2\mathrm{.}2$ Based on the force polygon for this problem$(1\mathrm{.}2),$ which element of the compression arch carries the highest load? Using concrete with

an allowable stress of $2400$ psi $,$ what is the minimum required cross$-$sectional area? $($Recall that stress, is force$/$area$.)$
