Engineering is best learned through application, not just theory. To help bring engineering concepts to life, I have developed a range of interactive tools that allow you to perform calculations, explore engineering principles, and visualise key concepts in a practical way. Designed for students, graduates, and experienced engineers alike, these tools combine hands-on learning with clear explanations to help you understand both the results and the underlying principles, making engineering knowledge more accessible, engaging, and relevant to real-world challenges.

• Material Comparison

  • This tool allows you to search, filter, and compare the mechanical, thermal, and physical properties of eighteen common engineering materials — including steels, aluminium alloys, titanium, polymers, and composites. Select up to four materials to view side-by-side bar charts across properties such as tensile strength, Young’s modulus, density, and thermal conductivity. Hover over any property for a plain-English explanation of what it means in practice.

• The Engineering Process tool

  • The Engineering Design Process Tool is an interactive learning resource that guides engineers, students, and educators through the eight key stages of engineering design, from problem definition and research through to prototyping, testing, iteration, and communication. Featuring detailed explanations, an interactive process map, a knowledge quiz, and a project checklist, the tool helps users understand how successful engineering solutions are developed in a structured, iterative way. Built using insights from leading engineering institutions, it provides a practical framework for applying design thinking to real-world engineering challenges.

• Milling Speeds and Feeds Calculator

  • The Milling Speeds and Feeds Calculator goes beyond standard machining calculators by combining cutting parameter calculations with fixture clamping force analysis. By entering cutter details, machining parameters, material type, and fixture information, users can estimate cutting forces, required clamping forces, feed rates, cutting speeds, and spindle power. Designed for manufacturing and production engineers, the tool helps bridge the gap between machining theory and practical fixture design, supporting safer and more reliable machining processes.

• Tolerance and Fit selector

  • The Tolerance and Fit Selector is an interactive engineering reference tool that calculates hole and shaft deviations for nine standard ISO 286 hole-basis fits across any nominal diameter from 1 to 500 mm. Enter a diameter and either select a fit designation directly — such as H7/p6 — or choose from a list of common application scenarios, and the tool returns the full tolerance band values, clearance or interference limits, and a visual tolerance zone diagram showing how the hole and shaft relate to the zero line.
