Figure 5 shows a wheel W pivoted at its centre, O and held stationary by a string and a spring. The tension in the strings is T and the force on the springs is F.
Use this information to answer 14 and 15
​(a)State how the magnitudes of T and F compare. Give reasons for your answer
(b)State what would happen to the wheel if the string snapped
answers
(a)T< F or F> TMoments of T and F about are equal; but the perpendicular distance from O to T perpendicular distance from O to F/ Resultant moment are zero
(b)Turn anticlockwise about O, OR Oscillate about O ![]() K.C.S.E Physics Q & A - MODEL 1996PP1QN13
