The diagram shows a wheel with a handle. Two forces, F1 and F2 of equal magnitudes are acting on the handle as shown in the diagram.
Justify your answer stated in (b).

Answer
Exam answer
Although F₁ and F₂ are equal, their perpendicular distances from O are unequal. Their clockwise and anticlockwise moments are therefore unequal, so the wheel is not in rotational equilibrium.
