Answer:

La ubicación de una fuerza igual a F₁ × 5/3 (que actúa hacia abajo), que debe aplicarse para el equilibrio estático, es 3 unidades a la derecha del pivote.

Encuentre el dibujo que muestra la posición y dirección de la fuerza requerida

Explanation:

5. Draw in what position and in what direction a force must be applied to the bar so that it remains horizontal and in static equilibrium, if F1 and F2 have the same magnitude

La información dada son;

La magnitud de F₁ = La magnitud de F₂

El punto de acción de F₁ = 3 unidades a la izquierda del pivote

El punto de acción de F₂ = 2 unidades a la izquierda del pivote

Para el equilibrio, el momento en sentido horario debe ser igual al momento en sentido antihorario

El momento en sentido antihorario. Mₐ sobre el pivote = F₁ × 3 + F₂ × 2 = F₁ × 3 + F₁ × 2

El momento en sentido antihorario alrededor del pivote = F₁ × (3 + 2) = F₁ × 5

El momento en el sentido de las agujas del reloj, M_c, para una fuerza F que actúa en el punto 3 unidades a la derecha del pivote si se da como sigue

M_c = F × 3

Para el equilibrio, tenemos;

F₁ × 5 = F × 3

F = F₁ × 5/3

Por lo tanto, la fuerza que debe aplicarse en el lado derecho en la marca de 3 unidades de la barra para el equilibrio estático = F₁ × 5/3.

An object in the shape of a thin ring has radius a and mass M. A uniform sphere with mass m and radius R is placed with its cent
madreJ [45]

Answer:

F = GMmx/[√(a² + x²)]³

Explanation:

The force dF on the mass element dm of the ring due to the sphere of mass, m at a distance L from the mass element is

dF = GmdM/L²

Since the ring is symmetrical, the vertical components of this force cancel out leaving the horizontal components to add.

So, the horizontal components add from two symmetrically opposite mass elements dM,

Thus, the horizontal component of the force is

dF' = dFcosФ where Ф is the angle between L and the x axis

dF' = GmdMcosФ/L²

L² = a² + x² where a = radius of ring and x = distance of axis of ring from sphere.

L = √(a² + x²)

cosФ = x/L

dF' = GmdMcosФ/L²

dF' = GmdMx/L³

dF' = GmdMx/[√(a² + x²)]³

Integrating both sides we have

∫dF' = ∫GmdMx/[√(a² + x²)]³

∫dF' = Gm∫dMx/[√(a² + x²)]³    ∫dM = M

F = GmMx/[√(a² + x²)]³  

F = GMmx/[√(a² + x²)]³

So, the force due to the sphere of mass m is

F = GMmx/[√(a² + x²)]³
