Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown in the figure. One load of P = 34 kips is applied to the assembly at A, two loads of Q = 30 kips are applied at B, and two loads of R = 33 kips are applied at C. The normal stress magnitude in aluminum rod (1) must be limited to 19 ksi. The normal stress magnitude in steel rod (2) must be limited to 35 ksi. The normal stress magnitude in brass rod (3) must be limited to 23 ksi. Determine the minimum diameter required for each of the three rods. P d = d = d3 = i B in. i in. i in.
