Question $3$: $(10)$

An angle $L3\frac{21}{2}\frac{1}{2}$ tension member has been connected in its flange with longitudinal welds as shown in

the Figure below. Grade $50$ is used $(F_y=50$ksi,$F_u=65$ksi $).$

$($a$)$ Compute the net area $A_n$

$($b$)$ Compute the shear lag factor $U($use all applicable cases$)$

$($c$)$ Compute the effective area $A_e$

$($d$)$ Compute the design strength of the tension member based on yielding strength $P{u}_u($Yielding$)$ and

rupture strength $P{u}_u($Rupture$).$ Show all details of your solution.
