These casters come in 12 twin-wheel models, made for a number of applications including medical equipment, hospital beds and stretchers, appliances, furniture and retail displays. All casters in a set can be locked simultaneously, using a fully-enclosed, positive mechanical brake and locking system. The casters are made out of lightweight, pressure-diecast aluminum shells, with standard gray polyurethane and gray rubber wheels. They are made to reduce swiveling and pushing effort, using roller bearing and twin-wheel design for low rolling resistance and smooth tracking. With the total lock mechanical brake in the "off" position, the wheels swivel and rotate freely, and swiveling and rotation are prevented in the "on" position. Load capacities range from 198 to 330 lbs. Available overall wheel heights are 138 mm for 5-inch wheel diameters, and 164 mm for 6-inch wheel diameters. The swivel radii are 106 mm for 5-inch casters and 131 mm for 6-inch casters.
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.
