A uniform meter stick swings about a pivot point which is a distance x = 27.4 cm from the end of the stick. What is its period of oscillation?

Solution:

Weight mg of the meter stick acts vertically down at its centre of gravity.

Torque acting on the meter stick about the pivot = τ = Force mg x Perpendicular distance of the line of action of the force from the pivot = mg x 0.226sinθ

For small displacement sinθ ≈ θ. Hence, τ = mg x 0.226 θ = m x 9.8 x 0.226 x θ = 2.215m θ

As the ...
