What do you mean by the term rope drive?
Sol: The ropes are circular in section. Rope-drive is mostly used when distance between the driving shaft and driven shaft is large. The frictional grip in rope drive is more than that in V-belt drive.
The ratio of tensions in this case will be same as in case of V-belt. Therefore ratio of tension will be as:
Ratio of Tension in Rope Drive:: T1/T2 = eµ.θ.coseca
