Homework Statement
Cords can withstand a maximum tension of 80N. What is the largest value of Fw they can support?
Homework Equations
Ft1 and Ft2 are 80.
FsysX = Ft1 sin 60 + Ft2 sin 70, but x doesn't matter
Fsys Y = Ft1 cos 60 + Ft2 cos 70  Fw
The Attempt at a Solution
80 cos 60 + 80 cos 70  Fw
Fw= 40+ 27
Fw = 67, when it should be 55.
