If one were to apply, for example, 60 Hz AC to a piezoelectric material, would the strain rate be 60 Hz?
I am not entirely sure if I am using "strain rate" in its proper sense; I use it merely to describe what I imagine would be the rate at which the material expands and contracts while exposed...
I'm working on a project that will find the coefficient of drag on bombs with various added drag features by modeling flow over the bomb at various angles of attack using CFD.
The problem is that I'm not sure if bombs with fins rotate while they are falling due to gravity, and if so, how I...
