Question
Which of the following is NOT an application of Pascal's principle?A manual car liftBicycle brakesAn electric fan Car brakesBlood pumped by the heart
Solution
Para responder a la pregunta, primero debemos entender qué es el principio de Pascal. El principio de Pascal establece que un cambio en la presión aplicada a un fluido encerrado se transmite sin disminución a todas las partes del fluido y a las paredes del recipiente que lo contiene.
Ahora, revisemos cada opción para determinar si es una aplicación del principio de Pascal:
-
A manual car lift: Un elevador manual de coches utiliza un sistema hidráulico para levantar el coche, lo cual es una aplicación directa del principio de Pascal.
-
Bicycle brakes: Los frenos de bicicleta, especialmente los frenos hidráulicos, también utilizan el principio de Pascal para transmitir la presión del fluido desde la palanca de freno hasta las pastillas de freno.
-
An electric fan: Un ventilador eléctrico no utiliza fluidos ni la transmisión de presión en un fluido. Funciona mediante un motor eléctrico que hace girar las aspas para mover el aire.
-
Car brakes: Los frenos de coche, especialmente los frenos hidráulicos, utilizan el principio de Pascal para transmitir la presión del fluido desde el pedal de freno hasta las pinzas de freno.
-
Blood pumped by the heart: La sangre bombeada por el corazón se mueve a través de un sistema de vasos sanguíneos, y la presión generada por el corazón se transmite a través de la sangre, lo cual es una aplicación del principio de Pascal.
Por lo tanto, la opción que NO es una aplicación del principio de Pascal es:
An electric fan
