Solution

According to the principle of moments, we have

Moment of load about the fulcrum = Moment of effort about the fulcrum

Load × Load arm = Effort × Effort arm

Given that the effort arm = 20 cm = 0.2 m, the minimum force E = 2 N

Therefore, the moment of load or the moment of force = 0.2 × 2 = 0.4 Nm

The moment of force needed to loosen the nut = 0.4 Nm
