Four forces are exerted on a disk of radius \(R\) that is free to spin about its center, as shown above. The magnitudes are proportional to the length of the force vectors, where \(F_1 = F_4\), \(F_2 = F_3\), and \(F_1 = 2F_2\). Which two forces combine to exert zero net torque on the disk? • Nerd Notes
