Problem $06\mathrm{.}056-$ Shaft A made of AISI $1020$ hot$-$rolled steel welded to a fixed support

In the figure shown, shaft A$,$ made of AISI $1020$ hot$-$rolled steel, is welded to a fixed support and is subjected to loading by equal and opposite forces $F$ via shaft $B.$ A theoretical stress$-$concentration factor $K_{ts}$ of $1\mathrm{.}6$ is induced in the shaft by the $\frac{1}{8}-$in weld fillet. The length of shaft A from the fixed support to the connection at shaft $B$ is $2$ ft $.$ The load $F$ cycles from $375$ to $500$ lbf $.$

Problem $06\mathrm{.}056.$b $-$ Determine the midrange and alternating stresses

What are the values of the midrange and alternating shear stresses at the critical section $($including the effects of stress concentration$)?($Round the final answers to three decimal places.$)$

The value of the midrange shear stress is $$ kpsi.

The value of the alternating shear stress is $$ kpsi.
