So I am reading a handout on transfer functions, and I got to this one example that doesn't seem right to me - which usually means I'm missing something.
It looks like this:
My understanding is that the numerator in H(s) is supposed to be the laplace transform of the input for the...
Thank you for your reply. I wanted to be sure I wasn't missing a more efficient way to go about it. I actually ended finding a fit curve with some stats software, and used that to solve for d, which came out to 37mm.
The problem:
The stepped bar with a circular hole, shown in Figure P5.75, is made of annealed 18-8 stainless steel. The bar is 12-mm thick and will be subjected to an axial tensile load of P=70kN. The normal stress in the bar is not to exceed 150 MPa. To the nearest millimeter, determine
(a)...
Thank you for clarifying and pointing that out. I would have went along after today assuming Δx was always nearly 0 for reversible adiabatic processes.
Strange. I double checked and the steam table in my physical textbook - which I was using last night - states 0.137, while my digital copy of the textbook, which is a few editions newer states 0.127.
That is an interesting question. I think I know how to go about it.
