Question

Between wheel and ground how much of traction force is required?

(a) High traction force

(b) Low traction force

(c) Infinite traction force

(d) No traction force

This question was addressed to me during an online interview.

I would like to ask this question from One Dimensional Problems in section One Dimensional Problems of Finite Element Method

Answer 1

Correct choice is (a) High traction force

To explain I would say: Traction or tractive force is the force used to generate motion between a body and a tangential surface, through the use of dry friction, through the use of shear force of the surface. In the design of wheeled or tracked vehicles, high traction between wheel and ground should be more desirable.
