**7. Resolve \( F_2 \) in the figure into its x and y components.**

Diagram Description:
- There is a triangle with an angled tension force \( F_2 = 600 \, \text{N} \).
- The angle from the horizontal x-axis is \( 45^\circ \).
- Another force \( F_1 = 450 \, \text{N} \) acts vertically upwards.

**8. Two forces act on the hook. Determine the magnitude of the resultant force.**

Diagram Description:
- A hook is shown with two forces: 
  - \( 500 \, \text{N} \) force at a \( 40^\circ \) angle below the horizontal.
  - \( 200 \, \text{N} \) force at a \( 30^\circ \) angle above the horizontal.

**9. Determine the magnitude and direction of the resultant force.**

Diagram Description:
- A hook with three forces acting on it:
  - \( 200 \, \text{N} \) vertically upwards.
  - \( 300 \, \text{N} \) horizontally to the right.
  - \( 400 \, \text{N} \) at an angle to the right, below the horizontal.

**10. Determine the design angle for connecting member A to the plate if the resultant force is to be directed vertically upward. Also, what is the magnitude of the resultant?**

Diagram Description:
