Homework Statement
0.5 kg bird lands on wire of telephone poles that are 50m apart. The wire sags 0.15m. What's the tension in the wire? Ignore weight of the wire
Homework Equations
The Attempt at a Solution
I figured out the angle that would be created (0.34 degrees) when the bird lands and when I go to make individual equations for the x and y components of the tension I put Fy=2Tsin(0.34) - W +N=0. When I check the answer they do not include the normal force (N) in the equation. Why is that? Is it because we are ignoring the weight of the wire?
