$6.(10$ pts$)$ A curved beam shown has a $2[$in$]$ DIAMETER SOLID CIRCULAR cross$-$section. The outer radius of the curved beam is $11[$in$].$ Moment M has a value of $3000[$lbf$*$in$].$ What is the magnitude of the maximum compressive normal stress at the left end of the beam, where it attaches to the wall?

The cross section is a circle, not a rectangle.
