A mass of 10kg placed 2 metres away from a pivot will have a moment of
- 196 NM.
- 150 NM.
- 980 NM.
Explanation
A moment is force times perpendicular distance, and the force from a mass is its weight, mass times g. So the weight is 10 x 9.8 = 98 N, and the moment is 98 x 2 = 196 Nm. Multiplying the mass directly without converting to weight would be incorrect.

Is this correct I thought it would have been 20nm

Hey!
First you must convert 10 kgs to newtons: 10 * 9.81
After that you must multiply result by 2. :)

people seem to confuse with this question..look at the units for the answer given..they want it in Newton metre..so,u need to convert your mass into weight.. weight=mass x 9.81..
