A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called ...

When you push or pull with a simple machine, you are applying a force and doing work. And, if you get more force out of a machine than you put into it, then that machine has a mechanical advantage.

A new children’s book, titled Simple Machines Made Simple, wants to demystify mechanical engineering for kids as young as a year old. It recently beat its Kickstarter goal by 700%—raising more than ...

Katie Aldworth grabs an empty wine bottle, puts it into a glass crusher, and then walks through her Maryland pottery studio with the end product: glass sand. After measuring out 275 grams, she pours ...

WAAAAAYYY back when I was in middle school physics they had some programs on our school computer that let you build simple machines. We basically built Rube Goldberg machines in the simulator to test ...

A research team of mathematicians and computer scientists has used machine learning to reveal new mathematical structure within the theory of finite groups. By training neural networks to recognise ...

Explains how pulleys work to lift heavy weights more easily. A fixed pulley changes the direction of force, allowing for easier lifting, while a movable pulley reduces the amount of force needed to ...
