What is the C or T, the X and Y components and the load of each member. Also when you put the answer, could you put it like it is on the image.
**Bridge Structural Analysis Exercise**

**Name:** ____________   
**Period:** _____  

This exercise involves analyzing a bridge structure that spans a 10ft wide creek. A 30lb downward force is exerted at the top center of the bridge. Your task is to calculate the load forces and the X and Y components for each member of the bridge. Round off your answers to two decimal places. For each member, specify whether it is in tension or compression.

All diagrams and triangle representations should be drawn on the back of this page or on an additional sheet. The bridge is assumed to be symmetrical and static.

**Diagram Explanation:**

- The bridge diagram is a symmetrical truss structure. The top central point is marked with a downward force of 30 lbs. 
- The X-axis runs horizontally, and the Y-axis runs vertically.
- Notations for key points of interest are A, B, C, D, E, and F.
- Angles of 58.00° and 48.98° are labeled to help with trigonometric calculations of forces.
- Support reactions Ay and Fy are shown at the base of the structure.

**Questions:**

- Calculate the forces Ay and Ey.
  - Ay = _________ lbs
  - Fy = _________ lbs

- Determine if this problem can be solved using the method of joints. Circle: YES / NO

- Note the equilibrium equations: 
  - ∑Fx = 0
  - ∑Fy = 0
  - ∑MZ = 0

**Table for Analysis:**

| Member | C or T | X  | Y  | Load |
|--------|--------|----|----|------|
| AB     |        |    |    |      |
| AC     |        |    |    |      |
| BC     |        |    |    |      |
| BD     |        |    |    |      |
| CD     |        |    |    |      |
| CE     |        |    |    |      |
| DE     |        |    |    |      |
| EF     |        |    |    |      |
| CF     |        |    |    |      |

**Instructions:**

1. Fill out the table for each member of the bridge, noting whether the member is in compression (C) or tension (T) and calculating the X and Y force components along with the total
