The 3 kg disk D is tied to the end of a string. The other end of the rope is tied to the knuckle in the center of a platform. If the platform rotates rapidly and the disc is left on the platform while stationary, determine the time required for the disc to reach the speed to break the rope. The maximum pulling force that the rope can withstand is 100N. Coefficient of kinetic friction between disc and platform H=0.1dr Hareket
