*** SKETCH ONLY DRAW the kinematic diagram & Free body diagram and label it for this problem

Transcribed Image Text:**Understanding Free-Body Diagrams: The Case of a Slender Bar**
**Scenario Description:**
A homogeneous slender bar \( AB \) of mass \( m \) and length \( L \) is released from rest in the position shown in Figure 2. The horizontal plane is frictionless.
**Tasks:**
1. **Draw the Complete Free-Body Diagram:**
- Respond on paper.
2. **Identify the Forces:**
- Determine how many forces act on the bar in the free-body diagram.
- Respond on Blackboard.
3. **Label the Force(s) Doing Work:**
- Identify and label which forces are doing work in the free-body diagram.
- Respond on Blackboard.
**Diagram Explanation:**
- **Bar AB**: The diagram shows a bar inclined at \( 45^\circ \) to the horizontal.
- **Length and Mass Indicators**: The bar is labeled with its length \( L \) and mass \( m \).
- **Angle Indicator**: The angle \( 45^\circ \) is shown between the bar and the horizontal surface.
- **Point A and B**: The two ends of the bar are marked as \( A \) (on the surface) and \( B \) (elevated).
The diagram helps visualize the situation for constructing a free-body diagram, identifying forces such as gravitational force, normal force, and any other relevant forces acting on the bar at rest before release.
