Bolted and Welded Joints

Bolted and Welded Joints

(OP)
I'm studying for my professional engineering exam and came across a problem that was never really covered in my courses in school. I was wondering if I could get some input from some people.

Design a bolted joint to attach a suitable american standard steel channel at an 18 degree angle to store a bundle (16) of 8x8x1/2 x 26 feet long square structural tubing. An identical member 16 feet away supports the other end of the bundle which can vary off center by two feet. The W18X55 vertical members and the channels are made from ASTM A242 steel,. Specify the number of bolts, pattern, material grade, diameter, length, and maximum torque.

Additionally, the same problem except a welded joint instead of a bolted joint. Specify the minimum weld pattern, the type of electrode to be used, and the size of the weld.

Thanks for any help!

Tell you what.

YOU first design YOUR joint to carry these loads. Show us the results, including YOUR assumptions. Then ask us to give YOU some criticisms of YOUR work. (Emphasis added deliberately.)

The test is intended to prove (to test that is) your abilities to solve real-world problems. If all we ever had to do was plug-and-chug numbers into spreadsheets, we'd be bureaucrats or tax accountants.

I made that mistake back in 1976 in a thermodynamics course. Prof didn't requrie homework every class, merely the mid-term and final test. I thought I knew it, I thought I had it all wired because I could follow every example in the book - but I didn't "practice" actually looking up numbers and values and interpolating from the tables. Didn't fail - but that 79 was the only "C" I ever got.

I'll never forgive myself for getting lazy. For not actually doing the work.

I'm with racookpe1978. Do your designs first then ask us to look at them. This forum is not for doing homework problems (or study exam problems).
