Reference no: EM132416624

A threaded bolt experiences a completely reversed axial load of 60,000 lb. The static factor of safety is 2.0, and the dynamic factor of safety is 3.0. K, = 2.0. The root radius of the threads is 0.020

(a) Compare the root area required for static and dynamic service for a high-strength bolt (<j0 = 180,000 psi, au = 200,000 psi).

(b) Repeat for a low-strength bolt (a0 = 30,000 psi, au = 50,000 psi). Use data in Prob. 12-1.

(c) Determine the ratio of the areas for low-strength and high-strength bolts for the static and dynamic conditions.
