You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Rolling-ring mechanical drives are simple, efficient, robust, and can eliminate the need for electronic controls. Bob Eisele, Amacoil Inc., Aston, Pa. Rolling-ring drives are friction drives that ...

The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...

One of the most common motion applications in automated machinery is linear motion due to its precision capabilities. Guide wheels are often critical to the dependability of such systems, especially ...
