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.

  • Physics -

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

  • Physics -

    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.
