Torque Formula:
| From: | To: |
Torque is a measure of the rotational force produced by a motorcycle engine. It represents the engine's ability to do work and is a crucial factor in determining a motorcycle's acceleration and pulling power.
The calculator uses the torque formula:
Where:
Explanation: The constant 5252 is derived from the relationship between horsepower, torque, and RPM. This formula allows you to calculate torque when you know the horsepower and RPM values.
Details: Understanding torque is essential for motorcycle enthusiasts, mechanics, and engineers. It helps in evaluating engine performance, comparing different motorcycles, and making informed decisions about modifications and tuning.
Tips: Enter the horsepower and RPM values. Both values must be positive numbers. The calculator will compute the torque in pound-feet (lb-ft).
Q1: Why is 5252 used in the torque formula?
A: The number 5252 comes from the relationship between horsepower, torque, and RPM. It's the point where horsepower and torque curves intersect on a graph when using lb-ft and RPM units.
Q2: What's the difference between horsepower and torque?
A: Torque measures rotational force, while horsepower measures the rate at which work is done (torque × RPM ÷ 5252). Torque gives you acceleration, while horsepower gives you top speed.
Q3: What is a good torque value for a motorcycle?
A: This varies by motorcycle type. Sport bikes typically have higher torque values than cruisers. Generally, higher torque means better acceleration, but the ideal value depends on the intended use of the motorcycle.
Q4: Can I use this calculator for other engines?
A: Yes, this formula works for any internal combustion engine, not just motorcycle engines.
Q5: How does gear ratio affect torque?
A: Gear ratios multiply torque. Lower gears provide more torque multiplication, which is why motorcycles accelerate faster in lower gears.
