Explain Trial 2: calculate the % difterence berween torque 1 and 2 Are the magnitudes of the torques equal?Explanation / Answer
PART:A
Trial 1:
Torque 1 : 0.211
Torque 2 : 0.216
% difference = ({0.216 -0.211} / 0.216) = 2.3 %
Yes, magnitude of both the torque are equal.
Trial :2
Torque 1 : 0.049
Torque 2 : 0.762
% difference = ({0.762-0.049} / 0.762) = 93 %
No, magnitude of both the torque are equal.
