Question
### Part A

As shown, a truss is loaded with forces \(P_1 = 210 \text{ lb}\) and \(P_2 = 401 \text{ lb}\) and has the dimension \(a = 3.30 \text{ ft}\).

![Truss Diagram](truss-diagram)

#### Problem Statement
Determine \(A_x\) and \(A_y\), joint A's reaction forces’ magnitudes in the x and y directions, respectively, and \(C_y\), joint C's reaction force's magnitude in the y direction.

**Express your answers numerically in pounds to three significant figures separated by commas.**

+ ### Diagram Explanation:
    - The diagram depicts a truss structure with four joints labeled \(A\), \(B\), \(C\), and \(D\).
    - The truss consists of horizontal, vertical, and diagonal members connected at these joints.
    - Joint \(A\) is fixed, while joints \(B\) and \(C\) are supported in such a way that only vertical reactions occur at \(C\).
    - Forces \(P_1\) and \(P_2\) are applied at joints \(D\) and \(B\), respectively, where:
      - \(P_1\) is a downward force of 210 lb at joint \(D\).
      - \(P_2\) is a downward force of 401 lb at joint \(B\).
    - The distance between joints, denoted as \(a\), is 3.30 ft.
    - The coordinate system is defined with x and y axes for reference.

+ #### Diagram Details:
    - Distances between joints along the x-axis are labeled as \(a\) (3.30 ft) times 3, from joint \(A\) to joint \(C\).
    - The vertical distance from joint \(A\) to joint \(D\) is given as \(a\) (3.30 ft).

#### Answer Input
\[ A_x, A_y, C_y = \]

(Example Input: 125.0, -210.0, 401.0)
