A practical application of a physical law in the repair of a garage door. (CP)

Describes the scientists and the work they did to study mechanisms of stable complexes of cobalt (III) using kinetic methods. Traces the work from 1946 to the present. (MA)

A critical view of mechanical engineering technology curriculum. Technical Education is a supplement to Industrial Arts and Vocational Education. (Editor)

This paper explores the Victorian concept of social utility as applied to adult education, and seeks to identify early elements of professionalism associated with that concept. The exploration is conducted through the medium of mechanics' institutes in several English-speaking countries. (Author)

It's a cool field where the job prospects are hot. That's the message that a lot of trade associations and education organizations are trying to get out about heating, ventilation, air conditioning and refrigeration (HVACR), and they have the statistics to back them up. The Occupational Outlook Handbook from the Bureau of Labor Statistics says…

The 1890s was the heyday for the bicycle in the United States. By 1896, bicycle manufacturing was a major industry with 300 established firms. Interest in bicycling, or "wheeling" as it was known then, grew rapidly into a national craze during the latter part of the 19th century. In 1890, American manufacturers produced nearly 30,000…

Guns, slug-throwing weapons, have evolved as humans have increased their grasp of the mechanical arts. In the near future, however, it seems likely that soldiers' rifles operating at punishing cyclic rates of fire face the limits of physics and materials science--heat and speed will cost accuracy and distance. This article considers not only the…

As the world economy continues to evolve, businesses and industries must adopt new practices and processes in order to survive. Quality and cost control, work teams and participatory management, and an infusion of technology are transforming the way people work and do business. Employees are now expected to read, write, and communicate…

The mechanics portion of the PSSC course is taught using man-sized" carts and equipment. The students ride and propel the equipment themselves thereby experiencing the forces and acceleration involved. The experiments are carried out in the school gymnasium. (TS)

Describes a laboratory activity about measurement and its reliability for general education students. The measurement focuses on automobile speeds and allows for estimates of errors, experimental design, and relativity in addition to kinematical concepts. (DS)

Describes a new "discovery-oriented" laboratory course in physics for college freshmen. The subject matter was Newtonian mechanics with calculus. The aim was to teach experimental methods from design of the experiment, testing hypotheses and presentation of final report. The laboratory was successful in most of its objectives and got moderately…
