The passing air exerts a negative lift FL downward on the car.

- A vehicle drives around a flat circular corner with a radius of 105m. If the maximum coefficient of static friction between the wheels and pavement is 0.90, then what is the maximum speed that the car can maintain without skidding?arrow_forwardEngineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R = 180 m and bank angle 8, where the coefficient of static friction between tires and pavement is µs. A car (without negative lift) is driven around the curve as shown in Figure (a). Find an expression for the car speed Vmax that puts the car on the verge of sliding out, in terms of R, 0, and us. Evaluate Vmax for a bank angle of = 10° and for (a) μ = 0.51 (dry pavement) and (b) µs = 0.050 (wet or icy pavement).

- A car of mass 622 kg is driving around a curve with a circular arc of radius 20 m. If the car drives at a speed of 12 m/s, what is the minimum value of the coefficient of friction between the car's tires and the road that will keep the car on the road?arrow_forwardEngineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R = 190 m and bank angle θ, where the coefficient of static friction between tires and pavement is μs. A car (without negative lift) is driven around the curve as shown in Figure (a). Find an expression for the car speed vmax that puts the car on the verge of sliding out, in terms of R, θ, and μs. Evaluate vmax for a bank angle of θ = 12° and for (a) μs = 0.58 (dry pavement) and (b) μs = 0.044 (wet or icy pavement). (Now you can see why accidents occur in highway curves when icy conditions are not obvious to drivers, who tend to drive at normal speeds.)arrow_forwardThe coefficient of friction acting upon a 945-kg car is 0.850.
