Problem3: Many high-performance race cars are equipped with a spoiler system that is located on trunk of the car.Spoilers are necessary to improve the traction of the car in high-speed situations by providing an additional down force to minimize the lift coefficients.Following fig shows a retractable spoiler system that would elevate at approximately 50 miles per hour and retract at 10 mph (a)What task does this design satisfy and why? (b)Draw an unscaled kinematic diagram of the mechanism. (c)Calculate the degree of freedom (d)What type of six bar for this mechanism? (a)Precision Position 1 (b)Precision Position 2 (Fully Retracted) 20 Ibf 5 》 n办 (c)50%Elevation (d)Precision Position 3 (Fully Elevated) Figure P1.74 Solution: (a)motion generator,because we are concerned with both the position and the orientation of the floating spoiler link.
