Determine the stress on a grade 2, 5/8-11 fastener that is loaded in tension to 15,000 pounds force (lbf). Determine whether this load will create a permanent elongation or return to its original length when the load is removed.
What will be an ideal response?
The 5/8-11 has a basic pitch diameter of 0.566 in (Machineries Handbook)
Calculate the cross sectional area of the fastener and the corresponding stress created by the 15,000 lbf load.
Will the applied stress cause permanent elongation? The 15,000 pound load creates a stress of 59,524 psi which is more than the SAE Grade 2 minimum yield strength of 57,000 psi so the fastener will have some permanent elongation. Will the fastener break due to the load? No. The minimum tensile strength is 74,000 psi.
