Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...

Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...
