a) DRAW SHEAR AND MOMENT DIAGRAMS OF EACH MEMBER

To draw the shear force and bending moment diagrams for each member in this structure, we'll first need to break down the loads and reactions. The system consists of:

1. **Beam Segment AB (from A to B):** 
   - Length: 4 meters
   - Uniformly distributed load (UDL): 36 kN/m

2. **Beam Segment BC (from B to C):**
   - Length: 4 meters
   - UDL of 24 kN/m (entire span BC)

3. **Beam Segment CD (from C to D):**
   - Length: 2 meters
   - A triangular distributed load decreasing from 24 kN/m at C to 0 kN/m at D.

### Step 1: Support Reactions
- **At A**: A fixed support, which will provide vertical, horizontal reactions and a moment reaction.
- **At C**: A pin support, which will only have a vertical reaction.

To proceed with drawing the shear and moment diagrams, I'll first calculate the reactions at supports A and C using equilibrium equations.

### Equilibrium Equations:
1. Sum of vertical forces = 0
2. Sum of moments about any point = 0

I will calculate this step-by-step.It seems like I can’t do more advanced data analysis right now. Please try again later. 

You can, however, proceed with these steps manually to find the shear and moment diagrams:

1. **Find the reactions at supports A and C** by solving the equilibrium equations (sum of forces and sum of moments).
2. **Determine shear forces** at key points (A, B, C, D) based on these reactions.
3. **Integrate shear force diagrams** to create the bending moment diagrams.

If you'd like, I can explain these steps in detail or guide you through the process.

Would you like to continue with more clarification, or do you have any further questions?

Here are some related questions to expand your understanding:

1. How can you use the method of sections to verify shear and moment values?
2. What is the significance of the area under the shear force diagram?
3. How does the triangular load on segment CD affect the shear and moment diagrams?
4. Why are reaction forces necessary for drawing these diagrams?
5. Can you use superposition to simplify beam analysis?

**Tip**: Always start with equilibrium equations when analyzing any structure to avoid missing any critical reactions.
