Calcula en watts y en caballos de fuerza la potencia mecánica de una grúa que efectúa un trabajo de 60000 joules en 3 segundos

Physics
1 answer:
katrin2010 [14]3 years ago
4 0

Answer:

I. Potencia mecánica = 20000 Watts.

II. Potencia mecánica = 26 caballos de fuerza.

Explanation:

Dados los siguientes datos;

Trabajo realizado = 60000 julios

Tiempo = 3 segundos

Para encontrar el poder;

I. En vatios:

Potencia mecánica = trabajo realizado / tiempo

Potencia mecánica = 60000/3

Potencia mecánica = 20000 Watts

II. En caballos de fuerza;

1 vatio = 0.0013 caballos de fuerza

20000 Watts = 20000 * 0.0013 = 26 caballos de fuerza.

Potencia mecánica = 26 caballos de fuerza.

rewona [7]

Answer:

0.073 N-m

Explanation:

i = 12 A, l = 0.8 m, B = 0.12 T

The circumference of the loop is 0.8 m.

Let r be the radius of the loop.

2 x 3.14 x r = 0.8

r = 0.127 m

Maximum Torque = i x A x B

Maximum Torque = 12 x 3.14 x 0.127 x 0.127 x 0.12 = 0.073 N-m

What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit
Tresset [83]

The highest frequency sound to which the machine can be adjusted is :

  • 4179.33 Hz

<u>Given data :</u>

Pressure = 10 Pa

Speed of sound = 344 m/s

Displacement altitude = 10⁻⁶ m

<h3>Determine the highest frequency sound ( f ) </h3>

applying the formula below

Pmax = B(\frac{2\pi f}{v}) A --- ( 1 )

Therefore :

f = ( Pmax * V ) / 2\pi \beta A

 = ( 10 * 344 ) / 2\pi * 1.31 * 10⁵ * 10⁻⁶

 = 4179.33 Hz

Hence we can conclude that The highest frequency sound to which the machine can be adjusted is : 4179.33 Hz .

<u><em>Attached below is the missing part of the question </em></u>

<em>A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.31×105 Pa. The speed of sound in air is 344 m/s. What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit?</em>
