Question

During tractor running the tyre slippage can be controlled by ___________

(a) Increase tractor speed

(b) Decreasing load of tractor

(c) Increasing co-efficient of traction

(d) Decreasing pressure of tyre

I have been asked this question by my school principal while I was bunking the class.

This intriguing question originated from Tractor Tyre and Front Axle topic in chapter Farm Tractor of Farm Machinery

Answer 1

The correct option is (c) Increasing co-efficient of traction

To explain I would say: The force which can be used for traction divided by the weight on the running gear is known as the coefficient of traction:

Usable traction = coefficient of traction x normal force.
