Multiple-Concept Example 7 explores the approach taken in problems such as this one. The blades of a ceiling fan have a radius of 0.343 m and are rotating about a fixed axis with an angular velocity of +1.67 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +1.38 rad/s2. After 0.443 s have elapsed since the switch was reset, what is (a)the total acceleration (in m/s2) of a point on the tip of a blade and (b) the angle  between the total acceleration  and the centripetal acceleration  (See Figure 8.13b)?

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 20.6 m, and the other with a blade length of 38.4 m. Each blade is rotating with a constant angular speed of 3.73 rad/s, and the rotation is considered...
