Question

The ratio of the net pull produced to the dynamic normal load on the traction device is known as:

• A. Motion resistance ratio
• B. Net traction coefficient
• C. Tractive efficiency
• D. Wheel traction

Hint:

Remember the definitions:
Net traction coefficient = Pull Weight.
Motion resistance = Rolling resistance Weight.
Tractive efficiency = Power output Power input.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Traction is the ability of a wheel to transmit force.
Various terms are used to describe traction performance.

Step 2: Key Formula or Approach:
Net traction coefficient = Net pull Dynamic normal load.

Step 3: Detailed Explanation:
Net pull is the force available for useful work.
Dynamic normal load is the weight on the wheel.
Motion resistance ratio is the ratio of motion resistance to normal load.
Tractive efficiency is the ratio of output power to input power.
Wheel traction is a general term.
Thus, the ratio of net pull to dynamic normal load is the net traction coefficient.

Step 4: Final Answer:
The ratio of net pull to dynamic normal load is the net traction coefficient.
Hence, the correct option is (B).
