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=25 kips are applied at B, and two loads of R=37 kips are applied at C. The normal stress magnitude in aluminum rod (1) must be limited to 16 ksi. The normal stress magnitude in steel rod (2) must be limited to 32 ksi. The normal stress magnitude in brass rod (3) must be limited to 24 ksi. Determine the minimum diameter (in inches rounded to the nearest hundredths) required for rod 1. Determine the minimum diameter (in in rounded to the nearest thousandths) required for rod 2. Determine the minimum diameter (in inches rounded to the nearest hundredths) required for rod 3.
