Question

What is wheel’s force?

(a) Force = wheel torque * wheel radius

(b) Force = wheel torque + wheel radius

(c) Force = wheel torque/wheel radius

(d) Force = wheel torque – wheel radius

This question was posed to me by my school teacher while I was bunking the class.

My enquiry is from Traction and Traction Theory topic in division Farm Tractor of Farm Machinery

Answer 1

Correct choice is (c) Force = wheel torque/wheel radius

For explanation: Traction is a force which generated between tyre and soil surface and due to this force only, tractor pull loads and move forward. More technically, when powered wheel try to move on soil, this wheel’s force (wheel torque/wheel radius) try to break the soil.
