Homework Answers
as the yield strength of the bolt material is not specified the factor of safety value can't be calculated ,but i provided you complete analysis and the formula to reach the final step to calculate the factor of safety you just need to substitute the value of yield strength of bolt material you will get the answer right away,i hope you understand the concept a thumbs up will be really appreciated.

A steel plate of (0.5 in thickness) shown in the figure was fixed by four bolts of (0.5*13-UNC grade 4) to the vertical steel column of (0.6 in thickness) as shown in figure below. An inclined eccentric force F of 10 kips was subjected to the plate at point A. Calculate: (a) The maximum stress in the rivets. (b) Check the safety factor if the plate and wall have a tensile strength...

Part 1
A cantilever flexural member is fabricated by bolting two
identical cold-rolled steel channels back-to-back, as shown. The
cantilever beam has a span of L = 1300 mm and supports a
concentrated load of P = 500 N. The cross-sectional
dimensions of the built-up shape are shown, where d = 40
mm, w = 65 mm, and t = 3 mm. The effect of the
rounded corners can be neglected in determining the section
properties for the built-up shape....

Standard design practice, as exhibited by the solutions to Probs. 8-66 to 8-70, is to assume that the bolts, or rivets, share the shear equally. For many situations, such an assumption may lead to an unsafe design. Consider the yoke bracket of Prob. 8-61, for example. Suppose this bracket is bolted to a wide-flange column with the centerline through the two bolts in the vertical direction. A vertical load through the yoke-pin hole at distance B from the column flange...

Two sections of pipe are flange connected as shown. A total max
external load, P=5000 is applied repeatedly. Washers and joint
members are made out of steel, E=30Mpsi. (Pls show work for all
prob.)
Thread fasteners:
N=8 ?1/2-13 UNC SAE grade 8. with a standard hexagon head.
Fasteners are to be reused (non-permanent instalation and
lubricated.)

B) Factor of safety (nf) for infinite life based on Goodman's
fatigue theory

131- (3 marks) Figure below shows a bolted joint subjected to an external force P that fluctuates from 0 to 7 kips. The steel bolt specification is 5/8"-11 UNC, SAE grade 5 material with rolled threads. The clamped members are steel of length 1.25 in each (with a total length of 2.5 in). Plain wide washers are utilized at both ends of the bolt. [a]. Using the Goodman line,...
