Find length of belt:
Find length of belt which is required to drive a pulley of 500mm diameter running parallel at the distance of 12m from driving pulley of diameter 1600m.
Sol: Given Data
Diameter of driven pulley (D_{2}) = 500mm = 0.5m
Radius of driven pulley (r2) = 0.25m
Centre distance (X) = 12m
Diameter of driver pulley (D1) = 1600mm = 1.6m
Radius of driver pulley (r1) =0.8m
As there is no mention about type of belt
So we find out for both the cases. (i) Length of belt if it is open WE know that By putting all the value L = 27.32m
(ii) Length of belt if it is cross We know that:
By putting the value
