The dimber exerts force F on the knot. The three red cables knotted at O support the force F B(-40,0,20)in 8-30 PM Type here to search @ ^ 9/17/2017 1

Explanation / Answer

All three components of forces at O has to be balanced.

So, TOA *-8/sqrt(8^2 +6^2) + TOC =0

TOA*6/sqrt(8^2 +6^2) + TOB*-9/sqrt(9^2 +4^2) =0

TOB*4/sqrt(9^2 +4^2) = 264*9.8

Solving the equations, we get

TOA = 9702 N

TOB = 6370N

TOC = 7762 N
