Question

A wheel of diameter 2m is shown in figure 1.28 with axle at O . A force f=2N is applied at B in the in the direction shown in the figure. Calculate the moment of force about (1) the centre O and (2) the point A

please help me ​

Answer 1

Answer:

1. Diameter of the wheel=2m

         Radius=1m

                 MOMENT OF FORCE=force*distance from the center

                             =2N*1m

                         =2Nm

2.  point A

Moment of force=force *distance

                      =2N*2m

=4Nm
