Expert Solution
Step 1
In the diagram, I can observe 4 nodes, 1, 2, 3, and 4. So I will solve the problem for these 4 nodes.
- The angle of 70 N force is given as 65°
- The angle of 90 N force from positive x = 65° + 40° = 105°
The angle of 20 N force from horizontal will be given by the geometry (from the diagram given in the problem).
Let's consider the 20 N force makes an angle ? with the axis,
Therefore,
