Hello,
I am preparing for the PE exam in 2 weeks and have some fundamental questions I would like to ask, starting with bolt stiffness. Many of these questions I know how to calculate, but I have been putting off understanding the "deeper" logic until now. Thanks in advance for your responses.
Question 1) In all of my PE references and problems, when calculating bolt stiffness, you use the nominal area instead of the tensile area. Why is this? It would seem that the thread area doesn't greatly contribute to the overall stiffness as if it did, we would use the nominal area in tensile stress calculations. We have the charts with tensile areas available, so this seems strange to me.
A few more questions forthcoming and thanks again.
