Trabajo y maquinas
Ciencia Fisica, Capitulo 6
| Question | Answer |
|---|---|
| potencia/power | cantidad de trabajo realizado en un segundo;se mide en vatios (W)/amount of work done, or the amount of energy transferred, divided by the time required to do the work or transfer the energy; meaasured in watts (W) |
| trabajo/work | la energia transferida cuando una fuerza mueve un cuerpo/transfer of energy that occurs when a force makes an object move; measured in joules. |
| fuerza de entrada/input force | fuerza que se aplica a una maquina/force exerted on a machine |
| fuerza de salida/output force | fuerza aplicada por una maquina/force applied by a machine |
| maquina/machine | aparata que facilita el trabajo/device that makes doing work easier by increasing the force applied to an object, changing the direction of an applied force, or increasing the distance over which a force can be applied |
| rendimiento/efficiency | medida de la cantidad de trabajo aplicado a una maquina que se convierte en trabajo de salida util por la maquina; se expresa como porcentaje/ratio of the output work done by the machine to the input work done on the machine, expressed as a percentage |
| ventaja mecanica(VM)/mechanical advantage(MA) | razon de la fuerza de salida a la fuerza de entrada/ratio of the output force exerted by a machine to the input force applied to the machine |
| cuna/wedge | plano inclinado con uno o dos lados inclinados/simple machine that is an inclined plane with one or two sloping sides |
| maquina compuesta/compound machine | dos o mas maquinas simples que operan juntas/machine that is a combination of two or more simple machines |
| maquina simple/simple machine | maquina que realiza trabajo con un solo movimiento de la maquina/machine that does work with only one movement--lever, pulley, wheel and axle, inclined plane, screw, and wedge |
| palanca/lever | barra libre de pivotear or de girar alrededor de un punto fijo/simple machine consisting of a bar free to pivot about a fixed point called the fulcrum |
| plano inclinado/inclined plane | superficie inclinada que reduce la cantidad de fuerza requeria para realizar trabajo/simple machine that consists of a sloping surface such as a ramp, that reduces the amount of force needed to lift something |
| polea/pulley | rueda acanalada con una cuerda, candena o cable que corre por el canal/simple machine that consists of a grooved wheel with a rope, chain, or cable running along the groove;can be fixed or movable |
| rueda y eje/wheel and axle | maquina simple que consiste en un tunel, a eje, conectado al centro de una rueda mas grande para que la rueda y el eje roten juntos/simple machine that consists of a shaft and axle attached to the center of a larger wheel;shaft and wheel rotate together |
| tornillo/screw | plano inclinado envuelto en un espiral alrededor de un cilindro/simple machine that consists of an inclined plane wrapped in a spiral around a cylindrical post |
