    Torque of a rotating disc with string

    Its not an exact question but a lab. What we are supposed to do is graph the angular acceleration of the disc on one axis, and the torque on another axis. The slope of that line is supposed to be the moment of inertia, which is what we are trying to find. I have the angular acceleration, but I...

    Torque of a rotating disc with string

    Homework Statement A disc is on a desk, with a rotation point underneath. A string is wrapped around it, and the end of the string has a mass attached to it. The string end is put over a pulley, and when the mass is dropped it causes the disc to rotate. We are given mass of the disc (80g)...
