The blades on modern wind turbines are typically 20 to 40 meters in length. Two different turbines have their blades attached with one end at the center of rotation. Consider two points, each at the outer end of a blade on each of the turbines: one with a blade length of 23.6 m, and the other with a blade length of 37.2 m. Each blade is rotating with a constant angular speed of 3.93 rad/s, and the rotation is considered...

The tail rotor section of a Black Hawk helicopter consists of four blades, each has a mass of 2 [kg), and a gear box that weights 38 [kg]. The center of gravity of each blade is 0.4 [m] from the rotational axis. The tail section is connected to the main body of the helicopter by an elastic structure. The natural frequency of the tail section is observed as 135 [rad/s]. During flight, the rotor operates at 850 [r/min). 1- Calculate...
