A 12.5 kN car has a 4000 mm wheelbase, with its center of gravity located 600 mm from the pavement and 1200 mm behind the front axle. Five people weighing on average 80 kg loaded the vehicle, shifting the center of gravity 125 mm nearer to the rear axle. What is the maximum tractive effort (N) that can be developed if the car is a front wheel drive? Use coefficient of road adhesion= 0.55.

- A car is traveling at 70 mi/h on a level section of road with good, wet pavement. Its antilock braking system (ABS) only starts to work after the brakes have been locked for 100 ft. If the driver holds the brake pedal down completely, immediately locking the wheels, and keeps the pedal down during the entire process, how many feet will it take the car to stop from the point of initial brake application? (The braking efficiency is 80% with the ABS not working and 100 % with the ABS working. Use theoretical stopping distance and ignore air resistance. Let frl = 0.02 when the brakes are locked, but complete the frl once the ABS becomes active.)arrow_forwardA race car with a 106-inch wheelbase has its weight evenly distributed between front and rear axles. At 150 mi/h, on a race track with = 1.0, the optimal brake force has 67.32% of the braking force on the front brakes. A new racing tire generates = 1.2. At 150 mi/h, what percentage of the braking force should now be allocated to the front to achieve optimal braking?arrow_forwardEstimate the power requires to accelerate a 1350 kg vehicle traveling at 48 kph up a 5% grade at the rate of 1.8 m/sec². The roadway has a straight alignment and a badly broken and patched asphalt surface. Rolling resistance of vehicle is 167 N/metric-ton, Air density = 1.2 kg/m³, and Aerodynamic drag coefficient = 1.3. Express power in watts using the formula P = RV. Use the formula for:arrow_forward
- A car is traveling up a 2% grade at 70 mi/h on good, wet pavement. The driver brakes to try to avoid hitting stopped traffic that is 250 ft ahead. The driver's reaction time is 0.5 s. At first, when the driver applies the brakes, a software flaw causes the anti-lock braking system to fail (brakes work in non-anti-lock mode with 80% efficiency), leaving 80 ft skid marks. After the 80 ft skid, the anti-lock brakes work with 100% efficiency. How fast will the driver be going when the stopped traffic is hit if the coefficient of rolling resistance is constant at 0.013? (assume minimum theoretical stopping distance and ignore aerodynamic resistance)arrow_forwardA Toyota Prius has the following attributes: Drag Coefficient Cd = 0.24, Frontal Area Af = 25.83 ft?, weight = 3064 lb, and Speed = 90 mph. Use air density p = 0.002378 slugs/ft3. If this car is driven up a 2% grade under a head wind speed of 10 mph compute the power required to overcome (a) Aerodynamic Resistance, (b) Rolling Resistance, and (c) Grade Resistance.arrow_forwardA 3500-lb vehicle (CD = 0.38, A_f= 26 ft^2, p =0.002378 slugs/ft^3) is driven on a surface with a coefficient of adhesion of 0.5, and the coefficient of rolling friction is approximated as 0.015 for all speeds. Assuming minimum theoretical stopping distances, if the vehicle comes to a stop 260 ft after brake application on a level surface and has a braking efficiency of 0.82, what was its initial speed (a) if aerodynamic resistance is considered and (b) if aerodynamic resistance is ignored?arrow_forward
- A vehicle weighing a 50 kN is moving at a constant speed around a circular curve. Neglecting the friction between the tires and the pavement and the centrifugal ratio (the ratio of the centrifugal force experience by the vehicle on the curve to its own weight) is 0.30. The degree of the curve is 5 degrees.a. Calculate the centrifugal force.b. Calculate the maximum speed the vehicle could move around the curve (in kph)c. If the skid resistance is 0.15, calculate the maximum super elevation that can be provided for the speed calculated from b.arrow_forwardA 11120 N car is designed with a 310 cm wheelbase. The center of gravity is located 60 cm above the pavement and 105 cm behind the front axle. If the coefficient of road adhesion is 0.6, what is the maximum tractive effort that can be developed if the car is (a) front-wheel drive and (b) rear-wheel drive? From the previous question, how far back from the front axle would the center of gravity have to be to ensure that the maximum tractive effort developed for front- and rear-wheel drive options is equal?arrow_forward6 A car is traveling at 20 mi/h on good, dry pavement at 5000 ft elevation. The front-wheel-drive car has a drag coefficient of 0.30, a frontal area of 20 ft2 and a weight of 2500 lb. The wheelbase is 110 inches and the center of gravity is 20 inches from the ground, 50 inches behind the front axle. The engine is producing 95 ft-lb of torque and is in a gear that gives an overall gear reduction ratio of 4.5. The radius of the drive wheels is 14 inches and the mechanical efficiency of the drivetrain is 90%. What would the acceleration of the car be if the driver was accelerating quickly to avoid a collision?arrow_forward
- Two cars are traveling on level terrain at 60 mi/h on a road with a coefficient of adhesion of 0.8. The driver of car 1 has a 2.5-s perception/reaction time and the driver of car 2 has a 2.0-s perception/reaction time. Both cars are side by side and the drivers are able to stop their respective cars in the same amount of distance after first seeing a roadway obstacle (perception/reaction plus vehicle stopping distance). If the braking efficiency of car 2 is 0.75, determine the braking efficiency of car 1.
