Figure 3-4
GIVEN: The bolted part shown in Figure 3-4. The load, P, is carried
by the part that is attached to the support by means of a bolt.
The bolt center is located at the center of gravity (CG) of the
cross section of the part. The bolt is a 5/8 inch diameter 11
UNC manufactured from 1045 cold-rolled steel with an ultimate
stress equal to 103,000 psi and an endurance limit equal to
47,000 psi. The bolt has ground threads, a stress area equal to
0.226 in', a stress concentration factor equal to 2.5 and a
coefficient of friction equal to 0.10. The initial torque on the
bolt is 500 in lb. The part is manufactured from steel and has
an area equal to 1.5 in'. The load on part, P, varies continuously
from 1000 lb to 5000 lb. The Modulus of Elasticity of the bolt
and part material is 30.0 x 106 psi.
ASSUMPTION: The length of the bolt and part are equal.
DETERMINE:
a. The Gross Area of the bolt

b. The Initial Force on the Bolt, Fo
c. The Spring Constant of the Bolt, kb and part, kp
d. The Average Load on the Part, Pavg
e. The Range of Load on the Part, P,
f. The Average Force on the Bolt, Favg
g. The Range of Force on the Bolt, Fr
h. The Average Stress on the Bolt, sigmaavg
I. The Range of Stress on the Bolt
J. The Factor of Saftey for the bolt
