Physics

Two brass rods AB and BC, each of uniform diameter, will bebrazed together at B to form a nonuniform rod of total length L=110m that will be suspended from a support at A as shown. Knowing thatthe density of brass is ρ=9000 kg/m3 and the diameter of AB is c=16mm, Determine (a) the length of rod AB for which the maximum normalstress in ABC is minimum, (b) the corresponding value of themaximum normal stress.
