We know that Torque=F×S
Since all forces applied are equal ie a constant we can say T is directly proportional to St, or displacement.
(i) C has least momentum as its distance is less.
(ii) A has greatest momentum for similar reason
(iii) A and B are clockwise. C is anticlockwise.
(iv) Res. torque =F×0.6 -(F×0.9 +F×0.8)
=0.6F-0.72F
=-0. 12F
=-0. 12×4
=-0. 48 Nm
