To create the free-body diagram for the 30-N bag suspended on strings \( A \), \( B \), and \( C \), based on the provided image, follow these steps:

### Understanding the setup:
- The 30-N weight is acting downward due to gravity.
- Three strings are attached to the weight:
  - String \( A \) is at a 60° angle to the horizontal on the left.
  - String \( B \) is at a 50° angle to the horizontal on the right.
  - String \( C \) is vertical and holds the 30-N weight.

### Drawing the free-body diagram:
1. **Forces acting on the object**:
   - **Weight (W)**: A downward force of 30 N representing the weight of the bag.
   - **Tension in string C (T_C)**: This tension acts upward, directly balancing part of the weight since it is vertical.
   - **Tension in string A (T_A)**: Tension in string A is inclined at 60° to the horizontal. It will have two components:
     - A horizontal component: \( T_A \cos(60°) \)
     - A vertical component: \( T_A \sin(60°) \)
   - **Tension in string B (T_B)**: Tension in string B is inclined at 50° to the horizontal. It will have two components:
     - A horizontal component: \( T_B \cos(50°) \)
     - A vertical component: \( T_B \sin(50°) \)

2. **Free-body diagram**:
   - At the point where the strings meet:
     - There is a downward force of 30 N (the weight of the bag).
     - The vertical components of \( T_A \) and \( T_B \) work together with \( T_C \) to balance this weight.
     - The horizontal components of \( T_A \) and \( T_B \) must balance each other since there is no horizontal movement.

I'll summarize the equations for you below:

### Equations for equilibrium:
1. **Vertical force equilibrium**:
   \[
   T_A \sin(60°) + T_B \sin(50°) + T_C = 30 \, \text{N}
   \]
2. **Horizontal force equilibrium**:
   \[
   T_A \cos(60°) = T_B \cos(50°)
   \]

Now that you have the forces and equations, you can solve for the tensions \( T_A \), \( T_B \), and \( T_C \).

Let me know if you'd like me to solve these equations in detail!

Do you have any questions, or would you like a detailed step-by-step solution for finding the tensions?

Here are 5 questions to consider:
1. How do the angles affect the tension in the strings?
2. What happens if the weight of the bag changes?
3. How would the system behave if there were no string \( C \)?
4. How do you calculate the components of forces acting at an angle?
5. Why must the horizontal components of tension forces balance?

**Tip:** Always resolve forces into their horizontal and vertical components when analyzing systems with inclined forces.

Draw the free-body diagram for the 30-N bag suspended on strings as shown in the given figure. Then solve for the tension along strings A, B, and C.
