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 ...

GREENFIELD — While most teachers show their students how to simplify problems, Amy Fletcher likes to teach her students how to make the simplest tasks more complicated. The Greenfield-Central ...

Machines are all around us, helping us do tasks and work all day, every day. The most basic ones are deemed “simple machines,” but these were, and still are, some of the most essential technological ...

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 ...

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 ...
