Question:
In the picture below, two forces F1 and F2 act on a disc that can rotate freely through an axis perpendicular to the center of the disc. Both forces work under the same conditions and cause the object to rotate counterclockwise at a coaxial angular speed. If the angle ? is reduced with a constant magnitude of the F1 force, should F2 be increased or decreased or fixed to maintain a constant disc rotation speed?
