## anonymous one year ago Determine the slope triangle dimension s so that the horizontal components of the two forces shown are equal to magnitude and opposite in sense. Then find the resultant of the force system.

before we help you, I think it would be nice for you to show us how would you approach this problem

5. anonymous

well i got pretty much all the answer but im not sure about em. like for s, its equal 2.20

6. anonymous

show us

7. anonymous

for the resultant of 2 forces is equal 15.01 N

8. anonymous

show us how you got that

9. anonymous

gimme a sec

resultant forces is easy using component method, which I think you already have an idea

16. anonymous

the problem is the Fx is equal 0. and the Fy as u see have 2 forces on the same line

17. anonymous

which idk to combine em or what

18. anonymous

you were given a clue that both horizontal components are equal but at the same time opposite that is equal in magnitude but are opposite in directions

19. anonymous

horizontal component is our x component, right?

20. anonymous

yes

21. anonymous

so we got F2x and F1x which the total is equal zero

22. anonymous

I think it is more reasonable to show that they are opposite in direction if we preserved the angle as 140 degrees instead of 40 degrees for our second resultant force

23. anonymous

oh that is fine with resultant

25. anonymous

so we just need to show it and calculate it too? cuz i tried to do like that before to solve that problem, but then i changed my mind

26. anonymous

lol we can calculate it using component method

27. anonymous

well yeah

28. anonymous

the problem is how can we make sure the resultant is on the y line or not. cuz if its not, then we cant solve it easily

if you preserve the angle counter-clock wise or use the quadrant as your reference, you still end up with the same answer in the end it is up to you however comfortable you are

36. anonymous

thank you so much :)
