1. A meter rule is anchored at the point O and is free to rotate about an axis passing through O and
perpendicular to the plane of the meter rule. Forces F₁, F2, F3, F4 and F5 of equal magnitudes act on
the ruler at different locations. The magnitude of each force is 24 N and 0 =30°. The distances along
the ruler are given in cm.
