E = F/q

   = 5.2 N / (7* 10⁻⁵) C

   = 7.429 * 10⁴ N/C

La tension que se transmite en la cuerda BD es de 75 lb. Calcula el momento de fuerza generada por la cuerda respecto al punto C
Bas_tet [7]

Answer:

Mc = 1920[lb*in]

Explanation:

Para poder solucionar este problema debemos realizar un análisis estático, por tal motivo lo primero es realizar un diagrama de cuerpo libre con las respectivas fuerzas actuando sobre la barra ABC. DE igual manera calcular la geometría de la configuración mostrada.

El diagrama de cuerpo libre se puede ver en la imagen adjunta, con la solución de este problema.

Lo primero es determinar el angulo t, el cual por medio de las propiedades del triangulo rectángulo se puede determinar.

Con este angulo (t) ya determinado, fijamos la atención en el triangulo BCD, este triangulo no es rectángulo, pero por medio de la ley de senos podemos determinar el angulo omega.

Después de determinar el angulo omega, restamos el angulo (t) para poder determinar el angulo (a).

Seguidamente realizamos una sumatoria de momentos alrededor del punto C, utilizado las respectivas fuerzas con los ángulos descompuestos.

El momento en el punto C es de 1920 [Lb*in].

Nota: ya que no se menciona la fuerza en el punto A, esta se desprecia y no se tiene en cuenta en los calculos. En la imagen adjunta se puede ver el procedimiento desarrollado.

if the current in a wire is 2.0 amperes and the potential difference across the wire is 10 volts what is the resistance of the w
Pavlova-9 [17]

Answer:

R = 2Ω

Explanation:

Potential difference (V) = current (I) * Resistance (R)

V = IR

I = 2.0A

V = 10v

R = ?

V = IR

R = V / I

R = 10 / 2

R = 2Ω

The resistance across the wire is 2Ω

You place a penny on a turntable at a distance of 14.3 cm from the center. The coefficient of static friction between the penny
S_A_V [24]

Answer:

Time will be 2.13 sec

Explanation:

We have given that distance r = 14.3 cm ==\frac{14.3}{100}=0.143m

Coefficient of static friction \mu =0.4

Angular acceleration is given by \alpha =2.45rad/sec^2

We know that frictional force is given by F=\mu mg

And centrifugal force is given by F=\frac{mv^2}{r}

When coin just starts moving

\mu mg=\frac{mv^2}{r}

We know that v=\omega r , here \omega is angular velocity

According to first equation of motion we know that

\omega =\omega _{i}+\alpha t

As \omega _i=0

so \omega =\alpha t

\mu g=\frac{\left ( r\alpha t \right )^2}{r}

\frac{\mu g}{r}=a^2t^2

t=\frac{\sqrt{\frac{\mu g}{r}}}{α}

t=\frac{\sqrt{\frac{0.4\times  9.8}{0.143}}}{2.45}=2.13sec
