1. What is the Gear Ratio And Torque Equation?

The gear ratio and torque equation calculates the output torque from a gear system based on input torque and gear ratio. It demonstrates how mechanical advantage is achieved through gear systems in bicycles.

2. How Does the Calculator Work?

The calculator uses the gear ratio equation:

Where:

• \( Torque_{in} \) — Input torque (Nm)
• \( Gear\ Ratio \) — Ratio of output gear to input gear (dimensionless)
• \( Torque_{out} \) — Output torque (Nm)

Explanation: The equation shows how gear systems multiply torque, with higher gear ratios producing greater output torque.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for bicycle design, gear selection, and understanding mechanical advantage in cycling systems.

4. Using the Calculator

Tips: Enter input torque in Newton-meters (Nm) and gear ratio (dimensionless). All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is gear ratio in bicycles?
A: Gear ratio is the ratio between the number of teeth on the front chainring and the rear cog, determining mechanical advantage.

Q2: How does gear ratio affect cycling?
A: Higher gear ratios provide more torque for climbing hills, while lower ratios allow higher speeds on flat terrain.

Q3: What are typical gear ratios for bikes?
A: Mountain bikes typically have ratios from 0.6 to 3.0, while road bikes range from 1.0 to 4.0 depending on gear combinations.

Q4: Does higher gear ratio mean easier pedaling?
A: No, higher gear ratios require more force but provide more torque, making them better for climbing rather than easier pedaling.

Q5: How does this apply to electric bikes?
A: The same principles apply, though electric assist may reduce the need for extreme gear ratios in some situations.
