FT = ?
Fy = 750 N
FT = Fx
Horizontal Cable
(750N)Tan 30° =Fx
Fg = 750 N
FT = 433 N

3. A sign hangs motionless from two cables. Find the Tension in Cable 2
A sign hangs motionless from two cables. Find the Tension in Cable 2. Include the direction of the cable, also.
F1 = 85 N F2

54.6 N
Fg = 110 N
65 N + y2 = 110 N
y2 = 45 N
F2 =  = 39.4 above Horizontal
