I took a picture of the question to help.
I know that the moment of inertia for a rod (at one end, not the center) is:
1/3ML^2
And I know that the period of oscillation is:
T=2∏√(L/g)
But I don't know how to relate them... I tried doing Torque=Iα=Fdcosθ and solve in terms of Time... but it wasn't becoming the equation and I had a random ω I couldn't get rid of. And I don't think I'm allowed to use the oscillation equation at all since I'm supposed to be deriving it, I'm just not sure what to do.
