A disk-shaped platform has a known rotational inertia ID. The platform is mounted on a fixed axle and rotates in a horizontal pl
Zarrin [17]

Answer:

Explanation:

The angular momentum of that same disk-sphere remains unchanged the very same way before and after the impact of the collision when the clay sphere adheres to the disk.

 \mathbf{I_w} = constant.

The overall value of such moment of inertia is now altered when the clay spherical sticks. Due to the inclusion of the clay sphere, the moment of inertia will essentially rise. As a result of this increase, the angular speed w decreases in value.

Recall that:

The Kinetic energy is given by:

\mathbf{K = \dfrac{1}{2} Iw^2} \\ \\\mathbf{K = \dfrac{1}{2} lw*w}

where;

\mathbf{I_w} is constant and w reduces;

As a result, just after the collision, the system's total kinetic energy decreases.

Una cuerda de 20 pies se estira entre dos arboles. Un peso W cuelga del centro de la cuerda hace que el punto medio de la misma
Galina-37 [17]

Answer:

La magnitud de la masa del peso es 78.447 libras-masa.

Explanation:

La tensión es una fuerza de reacción de la cuerda causada por la acción de una fuerza externa. En este caso, esa fuerza externa es el peso que cuelga en el centro de la cuerda. Abajo hemos adjuntado una representación simplificada del enunciado.

Por las leyes de Newton, tenemos la siguiente ecuación de equilibrio conformada por tres fuerzas:

\vec T_{1} + \vec T_{2} + \vec W = (0, 0)\, [N] (1)

Donde:

\vec T_{1}, \vec T_{2} - Tensiones a cada lado de la cuerda, en newtons.

\vec W- Peso, en newtons.

Si sabemos que \vec T_{1} = T\cdot (\cos \alpha, \sin \alpha), \vec T_{2} = T\cdot (-\cos \alpha, \sin \alpha) y \vec W = W\cdot (0, -1), entonces tenemos la siguiente ecuación vectorial:

T\cdot (\cos \alpha, \sin \alpha) + T\cdot (-\cos\alpha, \sin \alpha) + W\cdot (0, -1) = (0,0)

T\cdot (0, 2\cdot \sin \alpha) = W\cdot (0, 1)

Esto permite reducir la anterior expresión a una fórmula escalar:

2\cdot T\cdot \sin \alpha = W

Donde \alpha es el ángulo de inclinación de la cuerda, medido en grados sexagesimales.

El ángulo de inclinación de la cuerda se determina mediante la siguiente fórmula trigonométrica inversa es:

\alpha = \tan^{-1} \left(\frac{2\,ft}{10\,ft}\right)

\alpha \approx 11.310^{\circ}

Si conocemos que \alpha \approx 11.310^{\circ} y T = 200\,lbf, entonces la magnitud del peso es:

W = 2\cdot (200\,lb)\cdot \sin 11.310^{\circ}

W \approx 78.447\,lbf

En el Sistema Imperial, las fuerzas son medidas en forma gravitacional, entonces la magnitud de la fuerza gravitacional del peso equivale a la magnitud de su masa. En síntesis, la magnitud de la masa es 78.447\,lbm.

La magnitud de la masa del peso es 78.447 libras-masa.
