Best ResponseYou've already chosen the best response.1Ok, 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)

Best ResponseYou've already chosen the best response.0not at all.just i know that i for x axis and j for y axis.

Best ResponseYou've already chosen the best response.1and that is all you need to know. are you familiar with the cartesian coordinate system? and how you write a point (x,y)?

Best ResponseYou've already chosen the best response.0it 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..

Best ResponseYou've already chosen the best response.1are 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

Best ResponseYou've already chosen the best response.1since 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

Best ResponseYou've already chosen the best response.1next lets take on F1. dw:1365392293558:dw remember SOHCAHTOA 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

Best ResponseYou've already chosen the best response.1does that make sense? I am sorry, my drawing got cut off. dw:1365392671955:dw

Best ResponseYou've already chosen the best response.0Ok,i get it.but is there a mistake?this is for f1 right?

Best ResponseYou've already chosen the best response.1this is for F1, i dont believe there is a mistake, but i am human haha, what is the mistake that you are noticing?

Best ResponseYou've already chosen the best response.1I 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

Best ResponseYou've already chosen the best response.1do you understand what I did? Like am i actually helping you? or confusing you more and should just quit trying to help? haha

Best ResponseYou've already chosen the best response.0yes,i had already understand it.don't feel like that,Dave.thanks again. :)

Best ResponseYou've already chosen the best response.1ok 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
