Question
Can someone please help me to solve the following question showing all work and needed diagrams. Please and thank you!
**Method of Sections**

**Objective:**
Using the method of sections (no other method is acceptable), determine the forces acting in members KJ, DL, and EI of the truss shown below and indicate whether the member is in tension or compression.

**Requirements:**
- Must show the following:
  - c. Free-body diagram of each section being analyzed.
  - d. Calculations.

**Diagram and Explanation:**

The truss diagram includes the following features:

- **Loads:** 
  - A 900 lb force acting downward at point L.
  - A 1500 lb force acting downward at point K.
  - A 1000 lb force acting downward at point J.
  - Another 1000 lb force acting downward at point I.

- **Support Details:**
  - Support A is a roller.
  - Support G is pinned.

- **Member Distances:**
  - The distances between vertical points are uniformly 8 ft apart.

**Truss Members:**
- Horizontal members include AB, BC, CD, DE, EF, FG.
- Vertical members include N, M, L, K, J, I, H.
- Diagonal members include various intersecting braces providing support between horizontal and vertical members.

Each section must analyze forces within the members specified (KJ, DL, EI) using the method of sections, which involves cutting through the truss and solving for forces in one part using equilibrium equations.
