a truly problem solving question worthy of a lot of thinking skills.

i can imagine a team of learners discussing topics on:
1. trigonometry
2. parallelogram law of additional of forces
3. current law of current carrying wires
4. same direction current wires attract & opposite direction current repel
5. logic thinking of bisecting/dividing the angle made by forces line of action
6. comparison of 3 inequalities relationship/equation
7. drawing conclusion thinking skills

i like this because it is interesting, requires many skills to solve problem
