Please do 6-40
### 6.4 The Method of Sections

#### Problem 6-39:
Determine the force in members BC, HC, and HG. After the truss is sectioned, use a single equation of equilibrium for the calculation of each force. State if these members are in tension or compression.

#### Problem *6-40:
Determine the force in members CD, CF, and CG and state if these members are in tension or compression.

### Diagram Explanation:

The diagram represents a truss with triangular and quadrilateral sections supported at two points, A and E. It is subjected to several external forces:

- A downward force of 2 kN at point A.
- A downward force of 4 kN at point B.
- A downward force of 4 kN at point C.
- A downward force of 3 kN at point D.

The truss spans a total length of 20 meters, divided into sections of 5 meters each:

- Section AH is 5 meters.
- Section HG is 5 meters.
- Section GF is 5 meters.
- Section FE is 5 meters.

Vertical heights from the ground are given for points E (3m) and F (2m), indicating the elevations of the support points.

The task is to calculate forces in specific members and determine whether these members experience tension or compression as a result of the applied loads.
