Question

Is traction a contact force?

Answer 1

Answer:

Traction forces act in directions parallel to contacting surfaces in rolling/sliding contacts, analogous to friction forces in pure sliding contacts. ... In general, traction refers to frictional forces that beneficially transmit mechanical power whereas friction is associated with energy loss and dissipative processes.
