Question

What is co-efficient of traction?

(a) C.O.T = (Total force output of the traction device in the direction of travel) + (Dynamic weight on traction device)

(b) C.O.T = (Total force output of the traction device in the direction of travel) – (Dynamic weight on traction device)

(c) C.O.T = (Total force output of the traction device in the direction of travel) * (Dynamic weight on traction device)

(d) C.O.T = \(\frac{Total \, force \, output \, of \, the \, traction \, device \, in \, the \, direction \, of \, travel}{(Dynamic \, weight \, on \, traction \, device)} \)

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

Question is taken from Traction and Traction Theory topic in section Farm Tractor of Farm Machinery

Answer 1

Correct answer is (d) C.O.T = \(\frac{Total \, force \, output \, of \, the \, traction \, device \, in \, the \, direction \, of \, travel}{(Dynamic \, weight \, on \, traction \, device)} \)

Explanation: The coefficient of traction is defined as the usable force for traction divided by the weight on the running gear. It can also be defined as the ratio of the total force output of the traction device in the direction of travel to the dynamic weight on traction device.
