I am trying to understand the amplification factor(Ap). Sorry for being all over the place with this post but this is my first time using these equations. Also I will have a P.E look it over I am just trying to get a feel for it. I have a column with a mass at the top with a fundamental...

I have an arm assembly that is made out of two square tubes. One is smaller than the other and extends in and out of the larger one. Their are small tabs welded to the walls of the tubes that prevent them from sliding completely out. The arm is loaded with a point load at the end of the...

I found this thread: http://www.eng-tips.com/viewthread.cfm?qid=81231 This should of been the question I asked in the first place. I am still debating what mode of stress defines my system. I am leaning towards doing simply supported and design for shear stress and make sure that the bending...

Actually this is more of a pin clevis design, the reason I mentioned sheaves was that I assummed similiar analysis. The current design is a two clevis design (one inside of the other). I have referenced "Schaum's Machine Design" for clevis design and he includes bending caculation for a...

Coppola, I am also doing shear stress calcs, I just thought I needed to include bending calcs as well. So based on what your saying the worst case for pins is shear stress.....Right?

Can the pins in pulleys/sheaves be modeled as fixed-fixed?...if so, what standards must be followed for hole sizing? Is their a standard to follow? I have always modeled them as pinned-pinned(symply supported), but I was asked this question and not sure about it. I also found this info on...

Anybody out there know how to calculate the forces on brake caliper brackets? Or know where I can get info on this... Sorry for my crude post....this is my first one.
