## Homework Equations

w = sqt(MgL/I)

T = 2pi/w

I = 1/12ml^2 + 1/3ml^2

L = l/4

## The Attempt at a Solution

I solved for I using the above equation 3, solved for L using equation 4, plugged these values into equation 1 getting angular velocity. Then I solved for T in equation 2 and I do not get the correct answer.
