The final maximum value is appr hately a third of the initial maximum value, 1.R =- = r 1.04/K 0-31) B Figure 1: Diagrammatic representation of a disk hung through its centre. The disk has a radius of r Part 1) 8- Co Lab Test 2 m = 1.64 kg. r=0.217 m Part 2) The disk is now released from this angle. The torque is no longer applied. What is the frequency of the resulting simple harmonic motion? Ha What driving frequency would cause this disk to undergo resonance? 1 = 1.65 Nm O = 30.2 N www U through its centre (Figure 1) A torque of 1.65 Nm needs to be applied to cause it to move through an angle of 30.2" and then stop. 0
