Difference between Traction and Tractive Force ?

Click For Summary
SUMMARY

The discussion clarifies the distinction between "Traction" and "Tractive Force," particularly in the context of wheels and road surfaces. Traction refers to the grip or friction between a wheel and the surface it moves on, enabling movement without slipping. In contrast, Tractive Force is the force exerted by a wheel to overcome resistance and propel a vehicle forward, often associated with trains. The terms are often confused, but understanding their specific applications is crucial for accurate communication in mechanical and automotive contexts.

PREREQUISITES
  • Basic understanding of physics principles related to force and motion
  • Familiarity with mechanical engineering terminology
  • Knowledge of vehicle dynamics and traction control systems
  • Understanding of friction and its role in vehicle performance
NEXT STEPS
  • Research the physics of friction and its impact on vehicle traction
  • Explore the role of tractive force in railway systems and train dynamics
  • Study vehicle dynamics, focusing on traction control systems in modern vehicles
  • Investigate the mathematical models used to calculate traction and tractive force
USEFUL FOR

This discussion is beneficial for mechanical engineers, automotive professionals, and students studying vehicle dynamics or mechanical physics, particularly those interested in the principles of traction and tractive force in transportation systems.

Difference between "Traction" and "Tractive Force"?

I need to know exactly what the difference is between "Traction" and "Tractive Force". The more specific and detailed the better.

I can find definitions of "Traction" but nothing really on "Tractive Force".

This is specifically in reference to wheels and road surfaces.

Back story. I have someone who insists on using (teaching) that everything related to wheels and surfaces is "Tractive Force" and discounts "traction". That I can't find a definition of "Tractive Force" that helps me has had me wondering about this for years.

Thanks for the help!
 
Physics news on Phys.org
A quick search on google indicated that the term "tractive force" seems to be mostly used in relation to trains...

Then the free dictionary says something like this: Noun 1. driving wheel - a wheel that drives a motor vehicle (transforms torque into a tractive force)

at http://www.thefreedictionary.com/driving+wheel

so I decided to ask the difference between tractive force and traction here.

So I'm wondering, what is the difference between tractive force and traction?

(The more detailed the better)
