The image shows a problem involving two members A and B that are subjected to forces. Let's address the questions based on the given image:

1. **Determine the magnitude and direction of the resultant of the forces applied to the bracket.**

   To find the resultant force, we need to combine the forces applied to members A and B, considering their magnitudes and directions. The directions are indicated by the angles with the horizontal or vertical axis as shown in the diagram.

2. **Specify why a designer would want to know this information (a) or otherwise.**

   A designer needs to know the resultant force to ensure the structural integrity and stability of the bracket and the attached members. This information is crucial for selecting appropriate materials, designing connections, and ensuring that the system can withstand the applied loads without failing.

3. **Explain how we can see that both members A and B are in compression.**

   Both members A and B are in compression if the forces acting along the members are directed towards the nodes or connection points. Typically, in the diagram, this would be seen by examining the direction of the forces applied and ensuring that they push the members rather than pull.

### Detailed Analysis

To solve this problem accurately, we need to:
- **Identify force vectors:** Break down the forces into their horizontal and vertical components.
- **Sum the forces:** Calculate the total force in the x-direction and y-direction.
- **Find the resultant:** Use the Pythagorean theorem to find the magnitude of the resultant force and trigonometric functions to determine the direction.
- **Check for compression:** Both members A and B are in compression if the internal forces in these members are directed towards their ends (nodes).

Here are some related questions that might help deepen your understanding:

1. How do you resolve forces into their components?
2. What is the importance of understanding the direction of forces in mechanical systems?
3. How can you determine if a member is in tension or compression from a force diagram?
4. What role does the angle of applied force play in the magnitude of the resultant?
5. How can the knowledge of resultant forces aid in the design of safer structures?

**Tip:** Always double-check the directions of the force components when calculating the resultant force to ensure accuracy in your analysis.

Two inclined members are supported at one end by a pin and the forces exerted by them on the bracket are shown. Both members are in compression, the force in A is 10 kN, and the force in B is 12 kN.
