George I. Alden
George I. Alden (22 April 1843 – 13 September 1926) was a mechanical engineer and academic innovator. Alden was raised in Templeton, Massachusetts and educated at Harvard's Lawrence Scientific School and taught mechanical engineering for twenty-eight years at Worcester Polytechnic Institute where he gained national recognition for his teaching style that combined practice with theory. In 1885 he co-founded the Norton Emery Wheel Company in Worcester, Massachusetts. He also invented a dynamometer for measuring the power of various machines and the first hydraulic elevator. He was a trustee of the Worcester Polytechnic Institute and a trustee of the Worcester Boys' Trade High School. He was a member of the American Society of Mechanical Engineers The American Society of Mechanical Engineers (ASME) is an American professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "cont ...

The Worcester Polytechnic Institute (WPI) is a Private university, private research university in Worcester, Massachusetts, United States. Founded in 1865, WPI was one of the United States' first engineering and technology universities and now has 14 academic departments with over 50 bachelor's, master's, and Ph.D. degree programs. It is Carnegie Classification of Institutions of Higher Education, classified among "R1: Doctoral Universities – Very high research activity". History Worcester Polytechnic Institute was founded by self-made tinware manufacturer, John Boynton (Worcester Polytechnic Institute), John Boynton, and Ichabod Washburn, owner of the world's largest wire mill. Boynton envisioned science schooling that would elevate the social position of the mechanic and manufacturer, but not necessarily teach the skills needed to become either. Washburn, on the other hand, wanted to teach technical skills through a sophisticated apprenticeship approach. Boynton consulted ...

Dynamometer
A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed ( RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp. In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agency, dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). Beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behavior, and tribology. In the medical terminology, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Elevator
An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. Elevators are used in agriculture and manufacturing to lift materials. There are various types, like chain and bucket elevators, grain augers, and hay elevators. Modern buildings often have elevators to ensure accessibility, especially where ramps aren't feasible. High-speed elevators are common in skyscrapers. Some elevators can even move horizontally. History Pre-industrial era The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes ( – ) built his first elevator probably in 236 BC. Sources from later periods mention elevators as cabs on a hemp rope, powered by people or ani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worcester Boys' Trade High School
Worcester Technical High School (WTHS) is a vocational-technical high school, part of Worcester Public Schools district in Worcester, Massachusetts, United States. It opened on August 28, 2006, replacing the old Worcester Vocational High School (formerly known as Worcester Boys' Trade High School from 1909 to about 1975) at 2 Grove Street. School history The school was also known for a period as Worcester Vocational Technical High School (WVTHS) beginning around 1975. When the David Hale Fanning Trade School (commonly called "Girls' Trade" or DHFTS) in Worcester closed its Chatham Street premises some years later, the curriculum, staff and student body transferred to WVTHS. Since many new non-technical areas of study were added by the merging of the two schools, the word "Technical" was dropped from the school's name. When the school moved to Green Hill, the name was once again changed to its current title of Worcester Technical High School. In 2014, President Barack Obama g ...
