1. What is Resultant Force of Forces at Right Angles?

Definition: This calculator determines the resultant force when two forces act at a 90-degree angle to each other.

Purpose: It helps in physics and engineering problems where perpendicular forces combine to produce a single resultant force.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem formula:

Where:

• \( F_r \) — Resultant force (Newtons)
• \( F1 \) — First force component (Newtons)
• \( F2 \) — Second force component (Newtons)

Explanation: When two forces act perpendicular to each other, their resultant is the square root of the sum of their squares.

3. Importance of Resultant Force Calculation

Details: Calculating resultant forces is crucial for understanding net effects in structural analysis, mechanical systems, and motion problems.

4. Using the Calculator

Tips: Enter the magnitudes of both perpendicular forces in Newtons. The calculator will compute the magnitude of the resultant force.

5. Frequently Asked Questions (FAQ)

Q1: What if the forces aren't at right angles?
A: This calculator only works for 90° angles. For other angles, you'd need to use vector addition with trigonometric functions.

Q2: Does this account for force direction?
A: This gives the magnitude only. The direction would be atan(F2/F1) from F1's direction.

Q3: What units should I use?
A: The calculator uses Newtons (N), but any consistent force unit will work as long as both inputs use the same unit.

Q4: Can I use this for more than two forces?
A: For multiple perpendicular forces, you'd need to combine them pairwise or use vector components.

Q5: What's the maximum number of decimal places shown?
A: Results are displayed to 3 decimal places for precision.
