AP Physics 1
5.6 Newton’s Second Law in Rotational Form
5.4 Rotational Inertia
5.3 Torque
A construction worker spins a square sheet of metal of mass \(0.040\,\text{kg}\) with an angular acceleration of \(10.0\,\text{rad/s}^2\) on a vertical spindle (pin). What are the dimensions of the sheet if the net torque on the sheet is \(1.00\,\text{N}\cdot\text{m}\)? Assume that the moment of inertia of a rectangle is \(I = \dfrac{1}{12}M(a^2+b^2)\).
