$4\mathrm{.}11$ PROBLEMS

In Problems $1$ through $7,$ using the same hypothetical machine member, cal$-$

culate individual stresses and then combine them to find the net resultant

stresses for each different combination of loading. In all cases, you should

determine the maximum stresses.

Axial load only. Determine the axial $($normal stress$)$ in the part

shown in Figure $4\mathrm{.}6.$
