yes,it is.

Ok, well how i was taught to do vectors was to use right triangle trig. Do you have a background in using i and j form? (which are also known as unit vectors)
Imtant
  • Imtant
not at all.just i know that i for x axis and j for y axis.
anonymous
  • anonymous
and that is all you need to know. are you familiar with the cartesian coordinate system? and how you write a point (x,y)?

it is like this? Ri=58 cos 30 degree+50 cos 135 degree+45 sod 112.3 degree + 40 cos 112.7 degree? it's for the i component..

  • anonymous
are you looking for the i and j of the entire system? or each vector on its own? because that equation you just posted would be for the entire system, and it still would not be correct
Imtant
  • Imtant
no,each vector.

since you are confused, the easiest vector to solve is for F4. F4 is moving in the positive x direction with a force of 40kN, think about this not so much as a force, but just as a point. And there is no pull in the y direction. so the force will will have a vector notation of 40i+0j

next lets take on F1. |dw:1365392293558:dw| remember SOH-CAH-TOA sin(30)=y/58 sin(30)*58=y 29=y cos(30)=x/58 cos(30)*58=x x=50.23 so the vector notation for F2= 50.23i + 29j

does that make sense? I am sorry, my drawing got cut off. |dw:1365392671955:dw|

Ok,i get it.but is there a mistake?this is for f1 right?
Imtant
  • Imtant
vector notation for f1?right?
anonymous
  • anonymous
this is for F1, i dont believe there is a mistake, but i am human haha, what is the mistake that you are noticing?
Imtant
  • Imtant
it is f2.

I solved for the vector in the first quadrant with the f value of 58kN. I'm not sure if you labeled them wrong or something, but that is the vector is solved for

  • Imtant
but it's ok,dave.thanks.
anonymous
  • anonymous
do you understand what I did? Like am i actually helping you? or confusing you more and should just quit trying to help? haha
Imtant
  • Imtant
yes,i had already understand it.don't feel like that,Dave.thanks again. :)
anonymous
  • anonymous
ok no problem! i just dont want to confuse you more! do you need more help? Just remember that when a vector is facing a negative direction, that part of the form will be negative i.e. F2, the form will take -i+j
