Consider a bolt with five radial dash markings on the top of the head. The bolt diameter is measured using calipers and is 0.373 inches. The thread pitch is 24TPI.
Assume the applied modulus is 29Mpsi.
What is the proof load Fp? Proof load I think is 2.52 mega lb
(b) For a non-reusable joint design, what should the torque specification be? Assume f= f_c = 0.15
(c) What is the separation load P0 for a joint using this bolt with: N = 2 bolts, km = 8 x 10^6 lbf/in , grip length l = 2 in, and the bolt is fully threaded (no shoulder)?
