Answer 2

could you explain the last picture? I understand everything else. I'm sorry, my professor didn't explain this chapter well

Answer 3

I kind of came up with my own reasoning: Since each force has a degree of 30, and 30 to the right. You made a triangle and set two corners have a 60 degree, and therefore the remaining force (m1) has 1500 G J hat since it has the same degree as the rest?

Answer 4

yes ı am just doing vectorel sum because force is a vectorel quantitywhen you add F4 and F2 you obtain a triangle with all angle 60 degree so you have same magnitude force in the y axis
