5. At its peak, a tornado is 46.0 m in diameter and carries 505-km/h winds. What is its angular velocity in revolutions per second?7. A single-engine helicopter has two rotors; a main rotor and a tail rotor. The main rotor has a diameter of 14.8 m and rotates at the rate of 420 rev/min while the tail rotor with a diameter of 1.64 m rotates at 3775 rev/min. What are the speeds, in m/s, of the tips of each rotor?

Rotating unbalance is also important in rotorcraft such as helicopters and prop planes. The tail rotor of a helicopter (the small rotor rotating in a vertical plane at the back of a helicopter used to provide yaw control and torque balance) as sketched in Figure 2.21 can be modeled as a rotating-unbalance problem discussed in this section with stiffness k 1 x 105 N/m (provided by the tail section in the vertical direction) and mass of 20 kg.The tail section...

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...
