Homework Statement
A uniform metal disk (M = 8.21 kg, R = 1.88 m) is free to oscillate as a physical pendulum about an axis through the edge. Find T, the period for small oscillations.
Homework Equations
[itex]I = mr^{2}/4[/itex]
[itex]T = 2\pi √(I/mgd)[/itex]
The Attempt at a Solution
I combined the formula together to get:
[itex]T = 2\pi √((mr^{2}/4)/(mgr))[/itex]
[itex]T = 2\pi √(r/(4g))[/itex]
But the answer is incorrect
