I have an aluminum bar, 3 mm high. It is secured at one end and oscillates up and down vertically on the other end. Measurements are taken at a point 100 mm away from the secured end.
I need to figure out what the length (L) of the top of the bar is at a particular amplitude of oscillation (A).
Any thoughts on how to accomplish this. I appreciate any help.
