Part A

Determine the largest intensity $\backslash ($ w $\backslash )$ of the uniform loading that can be applied to the frame without causing either the average normal stress or the average shear stress at section $\backslash ($ b$-$b $\backslash )$ to exceed $\backslash (\backslash$sigma$=19\backslash$mathrm$\{$MPa$\}\backslash )$ and $\backslash (\backslash$tau$=25\backslash$mathrm$\{$MPa$\}\backslash ),$ respectively.

Express your answer to three significant figures and include the appropriate units.
