a) State how the magnitude of T and F compare. Give reasons for your answer
b) State what would happen to the wheel if the string snapped

a) T is less than F i.e. T < F

moments of T and F about O are equal, but the perpendicular distance from O to T is greater than the perpendicular distance from O to F. The Resultant moment is therefore zero

b) The wheel would turn in an anticlockwise direction about O

Next: The diagram in Fig. 5 shows a beam of negligible weight balanced by a constant forces P and Q.
Previous: Fig. 2 shows a rigid body acted upon by a set of forces. The magnitudes of the forces are as follows: F1 = 3N, F2 = 6N, F3 = 3N, F4 = 4N, F5 = 3N and F6 = 3N.
