1. What is a Work Calculator by Coolie?

Definition: This calculator estimates the work done by a coolie (worker) based on the force applied and distance moved.

Purpose: It helps calculate the mechanical work performed when a coolie moves an object over a distance.

2. How Does the Calculator Work?

The calculator uses the fundamental work formula:

Where:

• \( W \) — Work done (Joules)
• \( F \) — Force applied (Newtons)
• \( d \) — Distance moved (meters)

Explanation: Work is calculated as the product of the force applied to an object and the distance the object moves in the direction of the force.

3. Importance of Work Calculation

Details: Calculating work helps understand energy expenditure, efficiency of labor, and proper compensation for physical work.

4. Using the Calculator

Tips: Enter the force applied in Newtons and distance moved in meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a typical force for a coolie?
A: An average coolie might apply 300-500N when lifting or moving heavy loads.

Q2: How does this relate to energy expenditure?
A: 1 Joule of work equals 1 Newton-meter of energy. This helps estimate calories burned during work.

Q3: What if the force isn't parallel to movement?
A: The calculator assumes force and movement are in the same direction. For angled forces, use \( W = F \times d \times \cos(\theta) \).

Q4: How can I estimate force if I only know mass?
A: Force (N) = mass (kg) × 9.8 (gravity). A 50kg mass requires about 490N to lift.

Q5: Why measure work in Joules?
A: The Joule is the SI unit of work/energy, making it standard for scientific calculations.
