WebTo find the torque, we take the time derivative of the angular momentum. Taking the time derivative of l → l → as a function of time, which is the second equation immediately … WebThe angular velocity ω is ω = 300 rev 1.00 min 2 π rad 1 rev 1.00 min 60.0 s = 31.4 rad s. The moment of inertia of one blade is that of a thin rod rotated about its end, listed in Figure 10.20. The total I is four times this moment of inertia because there are four blades. Thus, I = 4 M l 2 3 = 4 × ( 50.0 kg) ( 4.00 m) 2 3 = 1067.0 kg · m 2.
