Homework Statement
A 125 N traffic light is hanging from two flexible cables. The magnitude of the force that each cable applies to the 'eye ring' holding the lights is called the cable tension. Find the cable tensions if the light is in equilibrium.
I have attached a scan from the textbook which contains a diagram.
Homework Equations
Not sure exactly what equations are there, except pythagoras theorem for magnitude, SOH-CAH-TOA.
The Attempt at a Solution
I assigned the first tension cable (left one) as vector a, the second one (right one) as b and the traffic light as g.
a = (x1cos150, y1[/SUB/sin150)
b = (x2cos45, y2[/SUB/sin45)
g = (0, -125)
And I think: a + b + g = 0
Answer is: T1 = 125([itex]\sqrt{3}[/itex]-1) N; T2 = 87.5(3[itex]\sqrt{2}[/itex]-[itex]\sqrt{6}[/itex]) N.
Thank you!
