The problem presents a pulley system with two masses \( m_1 \) and \( m_2 \), positioned on a horizontal and vertical arrangement as shown in the diagram. There are angles \( \alpha \) and \( \beta \), and the distance \( d \) is a key parameter. Let's break down each part of the question:

### Part a) 
**Determine the distances \( |AC| \) and \( |CB| \) in terms of \( d \) and \( \alpha \).**

- The pulley at \( A \) forms an angle \( \alpha \) with the pulley at \( C \), and the horizontal distance between \( A \) and \( B \) is \( d \).

Using basic trigonometry:
- \( |AC| = d \cos(\alpha) \)
- \( |CB| = d \sin(\alpha) \)

### Part b)
**Determine the distance \( |Dm_1| \) between point \( D \) and the mass \( m_1 \) in terms of \( d \), \( \alpha \), and \( \beta \).**

From the diagram, the point \( D \) lies vertically below \( C \) and horizontally from \( m_1 \), forming angle \( \beta \).

Using geometry:
- The vertical distance is \( d \sin(\alpha) \).
- The horizontal distance depends on \( \beta \), likely involving a combination of angles and distances.

### Part c)
**Write the expression for the length of the cord that holds the system from mass \( m_1 \) to mass \( m_2 \) in terms of \( d \), \( \alpha \), and/or \( \beta \).**

This will likely involve summing the various segment lengths of the string, which requires careful trigonometric handling.

### Part d)
**Determine the minimum distance between the two masses \( m_1 \) and \( m_2 \) in terms of \( d \), \( \alpha \), and \( \beta \).**

Using optimization, we find the shortest path considering the angles and lengths.

En la figura 23 se muestra un sistema compuesto por poleas A y B con dos cuerpos de masa m1 y m2. La distancia entre las poleas es d y coincide con la distancia entre la polea B y el cuerpo de masa m2. El ángulo formado entre el cuerpo de masa m1 y las poleas es α, mientras que el ángulo de elevación respecto a la horizontal entre los cuerpos es β.
