1. The problem statement, all variables and given/known data A physical pendulum is created from a uniform disk of radius 12.0 cm. A very small hole (which does not affect the uniformity of the disk) is drilled a distance d from the center of the disk, and the disk is allowed to oscillate about a nail through this hole. If the period of oscillation is 1.00 s, find d For the physical pendulum in Problem 6, find the value of d that results in the shortest possible period of oscillation, and find the corresponding period 2. Relevant equations ωT = 2pi ω = sqrt(mgd / I for phys pendelum) 3. The attempt at a solution The first question involves using a quadratic which I've completely solved to be 3.35cm. The second part I know somehow utilizes derivative but I have no idea how.
