Question $4$: The weld is applied to connect two plates. If two plates are subject to design load $Tu=110$kips $($see below$),$ the design capacity corresponding to weld failure is $100$ kips, and the design capacity corresponding to the plate failure is $140$ kips, determine $(1)$ what is the failure mode of the connection, and $(2)$ whether the connection can resist the given load or not $(5$ points$)$
