For a specillc value of p" it rvas establishcd that the toreue introduced to the cross-sectionis226 nm. Dctcrnrine tlte anglc of trvist per unit length of the beam. A soiid brass cylinder with radius 50 nmt and length 700 mm is press-fitted, under plane stress conditions (o,=0) into an aluminum cylinder with outer radius 60 nun. The radial inrcrference between the two cylinders is 0. 2 mm. The press-fitted assembly is then installed as a cantilever beam carrying an end-load p. tlsing the tresca condition, determine the maximum load p before yielding will begin. You can assume that the aluminum wilt yield first. Indicate clearly where in the cross-section the yielding will start.
