    don't make the things overly complicated. the ring is in equilibrium. so the resultant of force is zero. it means that the force exerted by ring on rod is equal and opposite to F. let R be force exerted by ring. here i am assuming that friction is a component of the force R. on string then...

    so the problem was the scale which was too small or there was some other errors? and if you chose 4 m/s as one block each small block will be of 4/5 m/s = 0.8m/s while the values are given correct to 0.1 m/s the graph was small for the vales. as the values were given to one decimal place there...
