V.R = teeth on worm gear/no. Of thread.
T of worm/ T of worm gear = D of worm/D of worm gear.
50/T.w.g= 50/100,
T.w.g = 100,
V.R = 100/1= 100.
T of worm/ T of worm gear = D of worm/D of worm gear.
50/T.w.g= 50/100,
T.w.g = 100,
V.R = 100/1= 100.

As per system of pulley,
VR = Distance moved by effort/Distance moved by the load.
= PI * D * T/pi * d * t.
= 100 * 50/50.1.
= 100.
VR = Distance moved by effort/Distance moved by the load.
= PI * D * T/pi * d * t.
= 100 * 50/50.1.
= 100.

LT/r, where L= radius of the wheel,
T = no.of teeth in worm wheel,
r = radius of load drum.
50*50/25.
2500/25.
= 100.
T = no.of teeth in worm wheel,
r = radius of load drum.
50*50/25.
2500/25.
= 100.

V.R=distance moved by P(effort)/distance moved by W(load).
V.R=2*L/2*r/T=LT/r=50*50/25=100.
V.R=2*L/2*r/T=LT/r=50*50/25=100.

HERE,
VR = DT/2r
= 100 * 50/2 * 50
= 50.
VR = DT/2r
= 100 * 50/2 * 50
= 50.

Vr = RT/nr.
= 100*50/50.
= 100.
= 100*50/50.
= 100.

V.R = nD/D-d.
= 50*100/100-50.
= 100.
= 50*100/100-50.
= 100.

D/d.
100/50 = 2,
2*50 = 100.
100/50 = 2,
2*50 = 100.

Here Vr = DT/2r.
