(b) The aluminium wire will break if the tension in the wire exceeds 350N.
The wire is attached to the flagpole at B, 0.8 m from the wall.
The wire is at an angle of 20° to the flagpole.
Assess whether the wire will break. You should use the principle of moments, taking
moments about 0.
length of flagpole = 1.2m
mass of flagpole and flag = 15 kg
