Concrete is 'cheap' and it helps me sleep better than friction does. Just add more concrete.
To answer your question, no I have never seen anyone use it, nor have I ever considered using it.
Why buy a house somewhere that you are unhappy. Start looking for a job in a new location, maybe a bigger cutter. Chicago and Minneapolis aren't 'too' far away.
Are you sure you are dealing with a truss? Loads should only be applied at joints, and all members should be pin connected; this should alleviate your problem if I understand it correctly.
Bedrock can become weathered and decomposed. At one extreme, severely weathered rock no longer has any rock properties and is soil. A geotechnical engineer needs to decide if the bedrock is poor rock or if the underlying stratum is soil.

The above link is to another forum user's website containing a collection of useful documents. There are some steel catalogs for the era in your post.
Mu = 50 plf *14.7^2 * 12 / 8 = 16.21 k-in
Zx = 1.25 * 2.5^2 /4 = 1.95 in^3
M_allow = 36/1.67 * 1.95 = 42 k-in > 16.21 k - in
Looks like you are okay!!!!
But I am confused, is the 6" pipe your handrail or your guardrail? It is too big to be a handrail. I have never used the term "Kick bar"...
No comment on #1, other than if you can answer the questions in SDRM then you will probably do fine on the structural portion of the PE. Remember, it is nearly August - you have less than three months to study.
#2 Get the correct code. There are some things that are different between 13th and...
Why pay them? Just emphasize how you are helping them: Link
But more seriously, recent NYC starting salaries were around $60,000 - 67,000. Other (non big city) places were closer to the $50,000 to 56,000 range. Personally I would have thought the $50,000 was low, but the place offered a ~15%...
My company pays for one pair of steel-toed boots every year. My current 2.5 year old pair is still doing fine.
They also will buy me dinner and drink(s) when I am away from the home office, but I usually only expense for the food and pay for my own drinks.
Now that my side tangent is out of...
Thank you sro2ck, I had actually never known of Prandtls theory before. Luckily a simple google search taught me that it was different from my home-boy Terzaghi's theory by the simple relationship of...wait noooo...UFO, I am not ready to be abducted...I was just about to explain the difference...
Why is there a vertical pressure on your elements? Is your silo cylindrical? conical? upside-down conical? Are you referring to frictional down drag? Are you referring to the the vertical pressure from the granular material inside the silo?
If you clarify these questions I may be able to...
I came across a bunch of aerospace course pages a few weeks ago trying to find a resource on plain strain. I do not know the quality of this resource, but here is a link to a nonlinear FEM course with an Ebook (I believe the ebook is written by the aerospace faculty at University of Colorado...
