Answer for screen readers
The final answer is D, do all of the above.
More Information
When using a vector diagram to calculate resultant forces, it's crucial to ensure lines are proportional to force magnitude, directions are correctly indicated with arrows, and a scale/reference direction is included.
Tips
A common mistake is neglecting to include a scale or reference, leading to inaccurate results.
