amistre64 · Answer

using trig we can construct 2 equations in 2 unknowns if we know that all the opposing forces must equal out

amistre64 · Answer

b1+b2 = 64
a1 = a2

the trig helps us define the parts now

amistre64 · Answer

sin(35) = b1/F1,  b1 = F1 sin(35)
cos(35) = a1/F1, a1 = F1 cos(35)

sin(50) = b2/F2,  b2 = F2 sin(50)
cos(50) = a2/F2, a2 = F2 cos(35)

Hello I cant see your replies this site keeps disconnecting and reconnecting every 2 secs. And an error message pops up.

amistre64 · Answer

this reduce gives us a system of 2 equation in 2 unknowns

F1 sin(35) +  F2 sin(50) = 64

F1 cos(35) = F2 cos(35)

amistre64 · Answer

F2 cos(50) that is .... typo :)

I did. It is just with this site. My internet connection is fine.

amistre64 · Answer

yeah, the site gives us all headaches.  also the browser you use tends to add to or diminsh the effectiveness

Sorry but how did you come to the conclusion: b1+b2 = 64  and a1 = a2
