The equation of motion of a discrete linear system has the form of a second-order ordinary differential equation with three real and square coefficient matrices. It is shown that, for almost all ...

Back in the 1980s, Pacific Bearing Co. (PBC) invented and commercialized plain bearings, which were sized to be interchangeable with linear ball bearings. Plain bearings worked very well in certain ...

AutomationDirect has added second generation (Gen 2) linear motion slide actuators to its SureMotion line of motion control products. The SureMotion lineup includes both motor-ready actuator ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

Breaking into the world of auto racing is easy. Step 1: Buy an expensive car. Step 2: Learn how to drive it without crashing. If you’re stuck at step 1, and things aren’t looking great for step 2 ...

A rack and pinion steering system consists of a pinion (a circular gear) with a rack (a linear gear). The system works by converting a revolving motion into linear motion. Most cars, small trucks, and ...

A cam is a simple mechanism that converts rotary motion (movement that goes round in a circle) into linear motion (movement in a straight line). These mechanisms can be found in car engines, printing ...
