A uniform 2.0 kg cylinder can rotate about an axis through its center at O. The forces applied are: F1 = 5.70 N, F2 = 3.90 N, F3 = 4.30 N, and F4 = 7.00 N. Also, R1 = 12.8 cm and R3 = 4.50 cm. Find the angular acceleration of the cylinder.

    On has to know where the forces are applied, and in what direction with respect to the rotational axis. What is R1, R3?

    R1 is the radius from the centre of the cylinder's circle, and the R3 is the distance from R1 to another specific point also near the centre of the cylinder's circle.
