I don't routinely do drug screening for a pre-purchase exam, but some purchasers do request this and it's not a bad idea. If you're going to spend a lot of money buying a horse and have any questions, this would be worth doing, Harbin says. He notes that a broad screen will cost around $300 to $500.Such screening detects pain killers, sedatives, anti-inflammatory drugs, steroids, et cetera, in the horse's system.f you're going to spend a lot of money buying a horse and have any questions, this would be worth doing, Harbin says.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor.
WP Clipart. The torque of a motor is the amount of force that an engine generates. This force is used to rotate a lever arm attached to the engine, which in turn propels the entire vehicle.Torque determines the towing force of a vehicle as well as its rate of acceleration.nstructions. Calculate the length of the motor's lever arm from the data you have. The length should be expressed in feet, which may involve converting the units from meters. If necessary, you can use the conversion calculator provided in the resources section of this article.
