6/26 The experimental Formula One race car is traveling at 300 km/h when the driver begins braking to investigate the behavior of the extreme-grip tires. An accelerometer in the car records a maximum deceleration of 4g when both the front and rear tires are on the verge of slipping. The car and driver have a combined mass of 690 kg with mass center G. The horizontal drag acting on the car at this speed is 4 kN and may be assumed to pass through the mass center G. The downforce acting on the body of the car at this speed is 13 kN. For simplicity, assume that 35% of this force acts directly over the front wheels, 40% acts directly over the rear wheels, and the remaining portion acts at the mass center. What is the necessary coefficient of friction between the tires and the road for this condition? Compare your results with those for passenger-car tires. Also determine the combined normal force acting at the pair of rear tires. VAnswer = 1.167, N₁ = 8690 N 250 mm -1625 mm- PROBLEM 6/26 1385 mm→ B
