The document you've uploaded contains questions and examples from Chapter 5 on the "Equilibrium of a Rigid Body." Here's a brief breakdown of the content:

1. **Free-body diagram for member ABC**: Supported by a smooth collar at A, a roller at B, and a short link CD. Each force acting on the diagram needs to be explained.

2. **Supporting a 50-kg cylinder**: The task is to draw free-body diagrams for the frame, rod DC, segment consisting of rod AC, pulley B and rope, and pin C, while neglecting the weights of the members.

3. **Skeletal diagram of a hand holding a load**: A 2 kg load and 1.2 kg forearm have centers of mass at G1 and G2, respectively. The question is to find the force in the biceps CD and the horizontal/vertical reactions at the elbow joint B.

4. **Reactions at pin A and smooth peg B**: For a given member, the horizontal and vertical reaction components at A, and the normal force at B, need to be determined.

Would you like assistance with solving any specific problem from these examples? Feel free to share which one you're interested in!

Here are five questions to further your understanding:
1. How do you approach drawing a free-body diagram for a system with multiple supports?
2. What forces typically act on a smooth collar and a roller in static equilibrium problems?
3. How do you calculate the forces acting on a pin joint, such as at the elbow in the hand-holding problem?
4. How do you determine the normal force at a peg or roller in structural problems?
5. What are the steps to find reaction forces at a pin joint with both horizontal and vertical components?

**Tip**: When drawing free-body diagrams, always ensure you account for all external forces, moments, and reactions acting on the system.
