A uniform disk with a mass of 27.3 kg and a radius of 0.309 m is free to rotate about a frictionless axle. Forces of 90.0 N and 125 N are applied to the disk, as the drawing indicates.

(b) What is the angular acceleration of the disk?

• physics -

describe the drawing. I am not certain what is the axis of rotation, is it a diameter, or is it perpendicular to the disk, through the center? Where are the forces?
