Simple machines make work easier, not less work, says Rick Crosslin, scientist. He joined us today to demonstrate how simple machines work. In our case, Randy was the “load” and Amber was the “effort.

Explains how simple machines, such as levers, pulleys, wheels and axles, and inclined planes, work together to make tasks easier by trading force for distance or vice versa. It illustrates the concept ...

Ally Serritella and Jonathan Harper work on a simple pulley machine with Mr. Peralta. The fifth graders at Woodglen School, in Lebanon Township, Hunterdon County, have been working on a simple machine ...

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 ...

Physicists have devised an algorithm that provides a mathematical framework for how learning works in lattices called mechanical neural networks. It's easy to think that machine learning is a ...
