An artist designs a balanced mechanical sculpture using a lightweight 2.0 m (200 cm) horizontal rod suspended from a cable at its centre (the 100 cm mark). Three decorative metal components are suspended from different positions along the rod:
- Component A, of weight 6.0 N, is suspended at the 40 cm mark
- Component B, of weight 4.0 N, is suspended at the 145 cm mark
- Component C, of weight 2.4 N, is suspended at the 175 cm mark
Using the principle of moments, determine if the sculpture is in rotational equilibrium. Show your calculations.
