- Axial Loads Are Applied With Rigid Bearing Plates To The Solid Cylindrical Rods Shown The Normal Stress In Aluminum Rod 1 (193.21 KiB) Viewed 53 times
Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. The normal stress in aluminum rod (1) must be limited to 19 ksi, the normal stress in brass rod (2) must be limited to 24 ksi, and the normal stress in steel rod (3) must be limited to 13 ksi. Determine the minimum diameter required for each of the three rods. Assume P = 8 kips, Q = 3 kips, R = 17 kips and S = 28 kips. v (1 (1) VQ (2) B R D с First: Calculate the internal force (positive if tensile, negative if compresive) in rod (1). Use a FBD cutting through the rod in the section that includes the free end A. Answer: F₁ = i kips.
