The output power of a rotating shaft is measured by a dynamometer. The relationship for output power is: 2*F*L*N P = kW t* 106 Where: F force applied in (N), L length of the torque arm in (mm), N number of revolutions during time t, and t time for test run in seconds. And the test results were: F= 6 0.02 N, L=400 +0.5 0.1 mm, N=1350 .0 revolutions, and t=60 seconds Determine the magnitude and uncertainty of the measured power.
