Materials, thermodynamics, and mechanical design.
Thermodynamics is full of misconceptions. I explain why 100% efficiency is a pipe dream, why Carnot rules, and how to design better heat engines.
You're choosing materials wrong if you only look at strength. Machinability ratings, tolerances, and weldability matter more than yield strength. Here...
Cast aluminum's 450% machinability rating isn't just a number—it's a game-changer for small-batch production. Here's how to use it to cut costs and cy...
In machining, stiffness isn't strength. Aluminum's low E is often misread as weakness, but yield strength, machinability, and weight tell another stor...
When weight matters, aluminum wins despite lower stiffness. Here's how to size an aluminum frame correctly using real material data.
