10N

0.2 m

Spanner X

Moment of Force = Force X Distance of Force = 10N X 0.2m = 2 Nm

Moment of Force (Spanner X) = 2 Nm

20N

0.2 m

Spanner P

Moment of Force = Force X Distance of Force = 20N X 0.2m = 4Nm

Moment of Force (Spanner P) = 4Nm

Spanner Q

10N

0.4 m

Moment of Force = Force X Distance of Force = 10N X 0.4m = 4Nm

Moment of Force (Spanner Q) = 4Nm
