Unformatted text preview: PROBLEM 4.107 SOLUTION at ms section is made of a material that is assumed
to be elastoplastic. Denoting by Mr and 9,, respectively, the bending moment and
radius of mature at the onset of yield, determine (a) the radius of curvatme when a
couple of moment M= 1.25M, is applied to the bar, (15) the radius of curvature aﬁer the couple is removed. Check the results obtained by using the relatioin derived in Prob.
