Question

It is the relative movement of the wheel or track in the direction of travel for a given distance under load and at no load condition is known as

• A. Rolling resistance
• B. Rim pull
• C. Wheel slip
• D. Tractive efficiency

Hint:

Wheel slip is the loss of forward travel due to slipping of the driving wheel on soil.

Answer 1

The Correct Option is C

Step 1: In tractors, the wheel may rotate but may not move forward by the full theoretical distance due to soil resistance.

Step 2: The difference between theoretical travel and actual travel is called slip.

Step 3: Wheel slip compares the movement of the wheel under no-load and load conditions.

Step 4: If there is more slip, useful forward motion decreases and power loss increases.

Step 5: Therefore, the relative movement of wheel or track under load and no-load condition is called wheel slip. \[ \boxed{\text{Wheel slip}} \]
