Final answer:
The correct direction to turn the front wheels while parking your car in a downhill lane is towards the curb or towards the right side of the road.
Step-by-step explanation:
The correct answer is option turn the front wheels towards the curb or towards the right side of the road when parking your car in a downhill lane. This is known as reverse parking or downhill parking. By turning the front wheels towards the curb, it helps prevent the car from rolling downhill in case the parking brake fails. The angle of the turn will depend on the slope of the hill.
For example, if you are parking on a steep downhill slope, you would turn the front wheels almost parallel to the curb. If the slope is less steep, you might turn the front wheels at a slight angle towards the curb. The goal is to position the wheels in a way that they will hold the car in place and not allow it to roll downhill if the parking brake fails.
The correct answer is option: When parking your car on a downhill lane, the front wheels should be turned towards the curb or side of the road. This is to ensure that if your car begins to move, it will roll into the curb and stop rather than rolling down the street.
The principle here is similar to that used when navigating banked curves with your vehicle. Ideally, a banked curve is designed so that the normal force from the road provides the centripetal force needed for a car to take the curve at a certain speed without feeling lateral forces that would cause sliding or tipping.
Similarly, parking with your wheels turned appropriately makes use of the car's tendency to roll downhill in a way that prevents unwanted movement. It is akin to how objects behave in a viscous fluid or the forces felt when a bicycle passes you on the sidewalk.
All these physical phenomena are related to the principles of motion and forces acting on objects, which are fundamental concepts in physics.
