This is a problem where we are supposed to design a cam..
For the same harmonic motion describe above, show that for a fiven value of C and L, the cam angle must be limited by the relationship..
in order to avoid pointing or cusp of the cam surface.
I know a cusp or point occurs on the cam surface when both and
I also know that
So plugging in
I just need help simplifying so i can get the relation above
