$8 g N$ $8g N$

Explanation:

The moments must balance, so $24 \times 14 = F \times 42$ $24 xx 14 = F xx42$ , where $F$ $F$ is the force that must be applied. Hence $F = 24 \times \frac{14}{42} = 8$ $F=24 xx 14/42 = 8$ . Hence $8 g$ $8g$ , that is, the local weight of a mass of $8 k g$ $8kg$ , since one kilogram has a weight of $g$ $g$ Newtons. (Informally, it would require a "weight' of 8kg on the wheel to balance the 'weight' of 24 kg on the axle.)
