About this project

What you'll build: You'll create a user-friendly calculator (in a spreadsheet or simple code) that helps determine the overall gear ratio and output speed for a basic two-stage gear train, based on the number of teeth and input speed.

Why it's a good starter: This project uses familiar tools and breaks down the process into easy steps. You'll practice key mechanical concepts while building something immediately useful, with clear instructions and lots of support.

What you'll learn: You'll gain hands-on practice with gear calculations, basic software or spreadsheet skills, and organizing a simple engineering solution from start to finish.

Milestones

1. Setup & Plan

10 marks 5d

Submit a short plan outlining your calculator's purpose, the main features you'll include, and which tool (spreadsheet or Python) you'll use. Your plan should show you understand the basic requirements.

2. Core Build: Input & Ratio Calculation

28 marks 10d

Submit your first working version. It should let the user enter gear teeth counts for the two stages and calculate the overall gear ratio. Show your working formula(s) and a screenshot/code snippet.

3. Core Build: Output Speed Feature

30 marks 10d

Add a feature to accept an input (driver) speed and display the output (driven) speed. Submit your updated file/code and a screenshot or sample output for at least one test case.

4. Testing & Polish

18 marks 7d

Test your calculator with at least three different gear sets and input speeds. Fix any errors, improve clarity (labels, instructions), and submit screenshots or results for your tests.

5. Demo & Short Report

14 marks 7d

Prepare a brief report (1 page) and a short demo (video or annotated screenshots) showing how your calculator works and what you learned. Submit both files.
