The blades on the wind turbine are turning with an angular speed of ωo = 30 rpm in the clockwise direction. If the blade length is L = 36.6 m and they are given a constant angular acceleration of α= 0.2 rad/s2 in the clockwise direction, determine: (a) the angular velocity and (b) the magnitude of the acceleration of point A on the tip of the blade when t = 3 minutes.

7.26. The conversion of the kinetic energy of wind to electricity may be an attractive altemative to the use of fossil fuels. Typically, wind causes the rotor of a turbine to turn, and a generator converts the rotational kinetic energy ofthe rotor into electricity. Power generated by a wind turbine (Ws) can be estimated from the density of the air (p), wind speed (u), and turbine rotor diameter (D) using the following formula лD? 1 W. ти* х п, where...
