SUMMARY
The discussion centers on calculating the allowable load on a steel tube with specific parameters: length (L) of 14 inches, cross-sectional area (A) of 11 square inches, Young's modulus (Es) of 30 x 10^6 psi, and a strain (δ) of 0.008. The user initially calculated the load (P) using the formula δ=PL/EA, resulting in P=188,571.4 lb, and then applied the formula θ=P/A, yielding P=264,000 lb. However, the instructor indicated the correct allowable load is P=2,181.8 lb, prompting confusion regarding the axial tensile load and the calculations performed.
