Question

The tractor engine is designed to have:

• A. Maximum torque and maximum power produced at same engine speed
• B. Maximum torque at lower speed compared to speed corresponding to maximum power
• C. Maximum torque at higher speed compared to speed corresponding to maximum power
• D. Maximum torque at double the engine speed compared to speed at maximum power

Hint:

Tractor engines have high torque at low speeds for better pulling ability.
Maximum power occurs at higher speeds.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Tractor engines are designed with specific torque and power characteristics.
We need to identify the relationship between maximum torque and maximum power speeds.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the typical torque-power curve of a tractor engine.

Step 3: Detailed Explanation:
In tractor engines, maximum torque is usually produced at a lower speed.
Maximum power is produced at a higher speed.
This design allows for better lugging ability at lower speeds.
Thus, maximum torque occurs at lower speed than maximum power.

Step 4: Final Answer:
Maximum torque is at lower speed compared to maximum power.
Hence, the correct option is (B).
