Question
A joint is subject to a cyclic loading. There is an acceptable preload of 1,200 lbs, and
the axial load is fully reversed with an amplitude of 1,600 lb. THe tensile bolt area is
0.160 in^2. Ignore any design factors and (take all nd=1) and assume the loads
include the 1.2 bolt factor.
If the joint constant is 0.25, the alternate and means axial stress for the bolt are:
a) sa = 1,250 psi
sm = 0
b) sa = 1,250 psi
sm = 8,750 psi
c) sa = 2,500 psi
sm = 0
d) sa = 2,500 psi
sm = 7,500 psi
