E10. A weight of 8.0 N is located 12.0cm from the fulcrum on the beam of a simple balance. What weight should be placed at a point 5.0 opposite side in order to balance the system? cm from the fulcrum on the E11. (a) Two forces are applied to a merry-go-round with a radius of 1.3 m, as shown in this question's diagram. One force has a magnitude of 90.0 N and the other a magnitude of 40.0 N. What is the torque about the axle of the merry-go-round due to the 90.0-N force? (b) What is the net torque acting on the merry-go-round? (You'll have to determine the torque due to the 40.0N force first.) E12. A net torque of 93.5 N-m is applied to a disk with a rotational inertia of 11.0 kg m2. What is the rotational acceleration of the disk? thic acceleration?
