Question
I couldn’t solve this problem during lecture. Please help me out! Thank you. Answer both boxes or do not attempt please
The blades of a wind turbine are 40 m in length and rotate at a maximum rotation rate of 13 rev/min. (Enter the magnitudes.)
(a) If the blades are 5,800 kg each and the rotor assembly has three blades, calculate the angular momentum (in kg · m2/s) of
the turbine at this rotation rate. (Assume the turbine blades can be approximated as rods rotating about one end.)
(No Response) kg · m?/s
(b) What is the torque (in N · m) required to rotate the blades up to the maximum rotation rate in 5 minutes? (Assume the
blades start from rest.)
(No Response) N. m
