Thank you for replying.

Consider a radius ratio of 50:1 and a small linkage length, small gear will be rotating very fast, but its center of small gear will moving slowly, will there be any slipping?What provides the torque to small gear to rotate that fast?

Thank you.I got it by changing frames.Can you do the analysis using ground frame only, considering the string tension?

Can you please elaborate.

Large gear does not rotate..only the small gear.

since the end of the linkage is glued to center of the gear , centre of gear has the same velocity as the end of the linkage. Usually for pure rolling on ground, Vcenter=RxW I am asking if such relationship exists here.

Thank you.Sorry, I meant to ask about the dependency of angular speed on the length of linkage connecting gears[edited]. Long Linkage means high tangential velocity for the center of the small gear, but its angular speed remains independent.

1.Why does the angular speed of small gear depend only on larger gear only? 2.Why does the length of linkage connecting two gears does not have any influence on the angular speed of smaller gear? The first question can be answered by looking at slack and tightening of chain caused by rotation...
