Question:

A helicopter has two blades (see Figure 8.11); each blade has a mass of 240 kg and can be approximated as a thin rod of length 6.7 m. The blades are rotating at an angular speed of 44 rad/s.

(a) What is the total moment of inertia of the two blades about the axis of rotation?

(b) Determine the rotational kinetic energy of the spinning blades.

3.00 m 6,70 m Figure 8.11 Points 1 and 2 on the rotating blade of the helicopter have the same angular speed and acceler
