Question

The three rotor blades of a wind turbine can be considered to be long thin rods. Each of the rotor blades is 49 m long and has a mass of 55 Mg. Part Description A. Determine the mass moment of inertia of the three rotor blades about the axis of rotation. (include units with answer) B. What is the magnitude of the torque that must be applied to bring the turbine from rest to a speed of 19 rpm in 65 seconds? (include units with answer)

Step 1

Given: Length of each rotor blade (L) = 49 m Mass of each rotor blade (m) = 55 Mg = 55,000 kg The mass moment of inertia of a rod about its end is given by the formula I = (1/3) * m * L^2, where m is the mass of the rod and L is the length of the rod. Plugging Show more…
