A lifting machine moves with an effort, a distance of 200 cm, in order to raise it 0.5 m. The Velocity Ratio is
- 8.
- 4.
- 2.
Explanation
Velocity ratio is the distance moved by the effort divided by the distance moved by the load. The effort moves 200 cm (2 m) while the load rises 0.5 m, so VR = 2 / 0.5 = 4. The answer of 8 would require the effort to move 4 m, and 2 would halve the effort distance.

Hello.
0.5m= 50cm
200/50=4
0.5m= 50cm
200/50=4

The ratio of a distance through which any part of a machine moves to that which the driving part moves during the same time.
