Darina [25.2K]

Pregunta completa :

Un zapato de golf tiene 10 tacos cada uno con un área de 0.01 pulgadas en contacto con el piso suponga que al caminar hay un instante en que los tacos soportan el peso completo de una persona de 180 libras ¿cuál es la presión ejercida por los tacos sobre el suelo?

Responder:

12230825.435 pascal

Explicación:

Dado que:

Peso (W) = 180 libras

Número de tacos = 10

Área por montante = 0.01 in²

Área total (10 * 0.01) = 0.1 pulg²

Usando la calculadora de conversión:

180 libras = 81.647 kg

0.1 pulg² = 6.452 × 10 ^ -5 m²

Recordar :

Presión = Fuerza (Newton) / Área (m²)

Fuerza = masa * aceleración debida a la gravedad

Aceleración por gravedad = 9,8 m / s²

Presión = (81.647 * 9.8) / (6.452 * 10 ^ -5)

Presión = 800.1406 / 6.452 * 10 ^ -5

Presión = 12230825.435 pascal
