The performance of wind energy conversion systems (WECs) depends upon subsystems like wind turbine (aerodynamic), gears (mechanical), and generator (electrical).
In the ninth century, the Banu Musa brothers, in Baghdad, published the "Book of Ingenious Devices," which detailed many geared mechanical contrivances, and the tenth-century philosopher and astronomer al-Biruni (973-1048) describes a Box of the Moon — a mechanical lunisolar calendar that used eight gearwheels.
Gears, mechanical devices, work pieces, valves, gears, tile and hardware are just a few of the nonstructural elements salvaged from old factories.

The rotation is transferred from the A-Gear to the P-Gear similarly to conventional mechanical gears.
Working with gears and mechanical parts she finds at antiques markets, she makes intricate pieces in silver, bronze and gold.
After two races in which the setup of the car was geared toward mechanical grip — in Monaco and Canada — at Silverstone the teams aim for more aerodynamic grip.
Actions are driven by a hidden anatomy of spring-driven cogs and gears, 2,340 mechanical parts all, each one gilt or polished steel.
Kapiolani Community College is known for their culinary and medical careers, as opposed to Honolulu Community College, which is more geared towards mechanical and industrial careers.
