1. What is AMA?

AMA (Actual Mechanical Advantage) is the ratio of resistance force to effort force in a machine. It measures how much a machine multiplies the input force.

2. How Does the Calculator Work?

The calculator uses the AMA equation:

Where:

• \( F_r \) — Resistance force (N)
• \( F_e \) — Effort force (N)

Explanation: AMA shows how many times the machine multiplies the input force. Higher AMA means greater force multiplication.

3. Importance of AMA Calculation

Details: AMA helps evaluate machine efficiency and design. It's crucial for engineers and physicists working with simple machines.

4. Using the Calculator

Tips: Enter both forces in newtons (N). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between AMA and IMA?
A: AMA considers real-world friction, while IMA (Ideal Mechanical Advantage) is theoretical without friction.

Q2: What are typical AMA values?
A: AMA values vary by machine type but are always less than IMA due to friction.

Q3: How does AMA relate to efficiency?
A: Efficiency = (AMA/IMA) × 100%. Higher efficiency means AMA closer to IMA.

Q4: Can AMA be less than 1?
A: Yes, in machines designed for speed rather than force multiplication.

Q5: What units are used for AMA?
A: AMA is dimensionless since it's a ratio of two forces.
