From the given data,
No.of teeth in Worm wheel (T) = 50
Diameter of Effort wheel =100mm, so Radius (R)=100/2=50 mm
Diameter of Load Drum (d)=50mm,so radius(r) is 50/2= 25mm
Velocity Ratio for a single threaded worm and worm wheel is given by the formula
V.R = R x T / r
V.R = 50x50/25
V.R = 100

Velocity ratio for single thread is
V.R= D×T/d

V.R =TR/r
where,
T= No of teeth on worm wheel
R= radius of the effort wheel
r=radius of the worm wheel

Velocity ratio for single thread is
V.R= D×T/d
Where D is the diameter of wheel
d is the diameter of worn
V.R = 100(50/50) = 100
