Question

**Mechanical Systems: Analyzing Arm ABC & Crank CD**

**Description:**

An arm, designated as ABC, is connected through pins at point B to a collar and at point C to a crank, labeled CD. For this system, the effect of friction is neglected, which simplifies the analysis.

**Diagram Explanation:**

1. **Dimensions & Structure:**
- Arm ABC is segmented as follows:
- AB = 160 mm
- BC = 320 mm
- Additional structure measurements:
- Between A and the end of the arm is an additional 90 mm.
- A vertical height of 180 mm is marked from the horizontal.

2. **Connections:**
- Point B has a green collar which allows the arm ABC to pivot or slide.
- The connection at point C interfaces with the crank CD, where the arm attaches to aid in rotational motion.

3. **Forces and Angles:**
- At point A, a force \( P \) is applied at an angle \( \theta \).
- At point D, a moment \( M \) influences the system, enhancing rotational behavior.

4. **Crank CD Dimensions:**
- Length from C to D = 300 mm
- Horizontal length from D = 125 mm

**Objective:**

Draw the free-body diagram for members ABC and CD to identify forces, support reactions, and possible motions or equilibrium states.

This system is commonly analyzed to understand mechanical advantage, efficiency, and the relationship between linear and rotational motions in mechanical contexts.
