1. A 100N light is suspended from a beam with two wires. Both wires make angles of 40 degrees with the beam.(adsbygoogle = window.adsbygoogle || []).push({});

2. What is the tension in the wires?

3. Ok heres what I have so far...

Sum Fx: T2(cos 40)-T1(cos 40)=0

so T2=T1

Sum Fy: T2 (sin 40)+T1(sin 40+(-100)=0

so T2(sin 40)+T1(sin 40)=100

With subsitutions...

T1(sin 40)+T1(sin 40)=100

And T1=77.8N, T2=77.8N, and T3=100N

Is this correct? And does changing the angle change the final breakdown? Such as if the angle was 30 degrees vice 40 degrees??
