The engine of a model airplane must both spin a propeller and push air backward to propel
Question:
The engine of a model airplane must both spin a propeller and push air backward to propel the airplane forward.
(a) Model the propeller as three 0.20-m-long thin rods of mass 0.040 kg each, with the rotation axis at one end. What is the moment of inertia of the propeller?
(b) How much energy is required to rotate the propeller at 5500 rpm? Ignore the energy required to push the air.
