  • high torque

    the turning force applied to a shaft by two equal and opposing forces. Unlike thermal engines, electrical motors can supply their maximum torque at zero to very low forward speed. This makes it possible to start up slowly with the large loads often encountered in traction or hoisting.

  • hydrocarbons

    hydrogen carbides. Assembly of carbon and hydrogen atoms, according to a CnH2n type formula. They can be distilled to give a wide variety of products, including gasoline.

  • hydrogen

    while analyzing water by electrolysis in 1783, French chemist Antoine Lavoisier decided to call this gas "hydrogen" from the Greek word "hydro" for water and "gen" for creator. Etymologically speaking, hydrogen means "that which produces water".
