Part A The "eggbeater" wind turbine is stopped by using spoilers which consist of 20-lb blocks that slide out along the blades when the blades are turning. As the spoilers travel along the blade, they create a drag on the blade that slows and eventually stops the blade. The blade has the shape of a parabola, as shown in (Figure 1). The coefficient of static friction between the spoilers and the blades is μ=0.3. If it is observed that the spolers reach point A on the blade, determine the required minimum speed of the spoilers needed to maintain this position. Express your answer in feet per second to three significant figures. ΜΕ ΑΣΦ vec Submit Request Answer Part B ? ft/: Determine the normal force the spoiler exerts on the blade when in this position.
