The 700 Series line of stamped, steel-ratchet clutches include two models: Model 701, which weighs 10 oz and can handle 85 ft-lb of static torque, and Model 702, which weighs 11/2 lbs and can handle 170 ft-lb of static torque. Custom models are also available. The ratchet clutches are for machinery indexing, manual backstopping of conveyor belts, or overrunning in dual-motor set ups.

In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
