Homework Statement
Two supporting wires keep a flagpole in its
vertical position. The horizontal components of the tensions in
the supporting wires must be equal and opposite,
otherwise the pole will move laterally. The
vertical components may be different.
The longer wire forms a 30 degree angle with the ground, and
the shorter wire forms a 45 degree angle with the ground.
a Calculate the ratio of the tension in the
shorter wire to the tension in the longer wire.
b If the tension in the shorter wire is 600 N, calculate the magnitude of the tension
in the longer wire.
(Refer to picture) in the word document.
Homework Equations
