Imagine a bolted joint with a washer between the bolt and the surface.
Assuming the washer is always covered by the bolt head so it's getting a consistent load, does the washer's diameter impact the static friction being imparted on the surface?
I see two conflicting ways of viewing this...
Okay well then it seems I'm even more thoroughly confused than I originally thought. I still think I have the LHS correct but I'm not entirely sure about using the gradient/del in index notation. Does it matter if you move it around within the term? Such as, are the following terms equivalent...
