SUMMARY

Banked curves are designed to enhance vehicle acceleration by optimizing the normal force acting on a car during a turn. When a road is banked, the normal force has a component directed toward the center of the curve, which aids in maintaining the vehicle's trajectory. This design reduces the reliance on friction between the tires and the road surface, allowing for smoother and safer navigation of curves. Understanding the physics behind banked curves is essential for automotive engineers and road designers.

PREREQUISITES
  • Basic understanding of physics principles, particularly forces and motion.
  • Familiarity with the concept of normal force in physics.
  • Knowledge of circular motion and centripetal force.
  • Understanding of road design principles related to vehicle dynamics.
NEXT STEPS
  • Research the physics of circular motion and centripetal acceleration.
  • Explore the design principles of banked curves in civil engineering.
  • Learn about the impact of friction on vehicle handling in curves.
  • Investigate the role of vehicle dynamics in automotive engineering.
USEFUL FOR

This discussion is beneficial for civil engineers, automotive engineers, and physics students interested in the dynamics of vehicle motion and road design.

What are the physics use of edges on the curve roads?

it is some thing relates to the acceleration like when the car impact them the acceleration of the car decreasing that's all what i got

I'm sorry, I do not understand the question. Are you referring to the guard rails that are put on the sides of roads? They would apply a force on the car in order to change the car's direction of motion.
 
i mean why curves in the ways often banked?
 
You are talking about how the road is banked (sloped) such that it is higher on the outside of the curve, right?

It has to do with the support force (normal force) from the surface of the road.

If the road is banked, then the normal force (which points perpendicular from the surface) will have a component that points toward the center of the circle (the circle that the curve is part of).
