A uniform beam of mass 1.4 kg is pivoted at P, as shown. The beam has a length of 0.60 m and P is a distance of 0.20 m from one end. Loads of 3.0 kg and 6.0 kg are suspended at distances of 0.35 m and 0.15 m from the pivot, as shown. What is the torque that must be applied to the beam in order to maintain it in equilibrium?

1. A0.010 N m
2. B0.10 N m
3. C0.29 N m
4. D2.8 N m
