None Part AThe "eggbeater" wind turbine is stopped by using spoilerswhich consist of 20-lb blocks that slide out along theblades when the blades are turning. As the spoilers travelalong the blade, they create a drag on the blade thatslows and eventually stops the blade. The blade has theshape of a parabola, as shown in (Figure 1).

An older Rolls Royce Ghost is traveling at 25 mph on a roadway with good, dry pavement.The car has a C D = 0.32, 35 ft 2 of frontal area, and weighs 5,445 lb. The wheelbase is 129.7 inand the center of gravity is 25 in above the pavement and 60 in behind the front axle. Thevehicle is traveling on pavement at sea level. The engine produces a hefty 620 ft-lb of torqueand is in a gear of the transmission that provides a gear reduction of 5 to 1 with a 22 in wheelradius and 95% drivetrain mechanical efficiency. If the limo driver needs to accelerate hard inthe Ghost to avoid an accident, what would the acceleration be since it is a rear-wheel drive car?

6. In a Porter governor, the upper and lower arms are each 250 mm long and are pivoted on the axis of rotation. The mass of each rotating ball is 3 kg and the mass of the sleeve is 20 kg. The sleeve is in its lowest position when the arms are inclined at 30° to the governor axis. The lift of the sleeve is 36 mm. Find the force of friction at the sleeve, if the speed at the moment it rises from the lowest position is equal to the speed at the moment it falls from the highest position. Also, find the range of speed of the governor.
A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of θ just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? Finally, if the inclined plane became icy, and the rope didn’t break as the cask slipped, what would be remarkable about the lines of action of the W, N and T force vectors once equilibrium was re-established?
