1. What is Torque?

Torque is a measure of the rotational force required to lift or move an object. In this case, we're calculating the torque needed to lift a 10 kg weight using a rotating system.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque in Newton-meters (Nm)
• \( 10 \) — Weight in kilograms (kg)
• \( g \) — Acceleration due to gravity (9.8 m/s²)
• \( r \) — Radius in meters (m)

Explanation: The equation calculates the rotational force needed to lift a 10 kg weight at a given radius from the pivot point.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, selecting appropriate motors, and ensuring safe operation of lifting equipment.

4. Using the Calculator

Tips: Enter the radius in meters from the pivot point to where the force is applied. The radius must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: Why is the weight fixed at 10 kg?
A: This calculator is specialized for 10 kg weights. For other weights, the equation would need to be adjusted.

Q2: What are typical torque values for lifting applications?
A: Torque requirements vary widely depending on the radius. Even small radii can require significant torque for heavy weights.

Q3: Does this account for friction or efficiency losses?
A: No, this calculates ideal torque. Real-world systems should account for additional factors like friction and efficiency.

Q4: Can this be used for horizontal rotation?
A: This calculates torque needed to overcome gravity. Horizontal rotation would have different requirements.

Q5: How does radius affect torque?
A: Torque increases linearly with radius - doubling the radius doubles the required torque.
