The split ring shown has an inner radius $r_1=0\mathrm{.}6$ in$.$ and a circular cross section of diameter $d=0\mathrm{.}8in.$ Knowing that each of the $100-lb$

forces $P$ is applied at the centroid of the cross section, determine the stress at point A and at point $B.$

The stress at point $A$ is

ksi.

The stress at point $B$ is

ksi.
