1. What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. In this context, it represents the rotational force needed to lift a 100 kg weight at a certain radius.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( \tau \) — Torque (Nm)
• \( 100 \) — Mass (kg)
• \( g \) — Gravitational acceleration (9.8 m/s² on Earth)
• \( r \) — Radius or lever arm length (m)

Explanation: The equation calculates the torque required to counteract the gravitational force acting on a 100 kg mass at a given distance from the pivot point.

3. Importance of Torque Calculation

Details: Calculating torque is essential for designing mechanical systems, determining motor requirements, and ensuring proper lifting capacity in cranes and other lifting equipment.

4. Using the Calculator

Tips: Enter the radius in meters and gravitational acceleration (default is 9.8 m/s² for Earth). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the mass fixed at 100 kg?
A: This calculator is specifically designed for a 100 kg weight. For other weights, the equation would need to be adjusted.

Q2: What units should I use for radius?
A: The calculator expects radius in meters (m) for correct torque calculation in Newton-meters (Nm).

Q3: Can I use this for different gravitational accelerations?
A: Yes, you can adjust the gravity value for calculations on other planets or in different gravitational conditions.

Q4: What if my system has multiple weights?
A: This calculator handles a single 100 kg weight. For multiple weights, you would need to calculate torque for each and sum them.

Q5: How does this relate to motor selection?
A: The calculated torque helps determine the minimum torque requirement for a motor needed to lift the 100 kg weight at the specified radius.
