Question

A machine displaces a load of 125kgf through a distance of 0.30m, while an effort of 12.5kgf acts through a distance of 4.0m. Calculate the velocity ratio.

Answer 1

1. Definition:

Velocity ratio:

It is the ratio of the distance moved by the effort to the distance moved by the load.

Velocity ratio = $\frac{dis\tan cemovedbyeffort}{dis\tan cemovedbyload}$

2. Solution:

Given that,

load = 125 kgf

effort = 12.5 kgf

distance moved by load = 0.30 m

distance moved by effort = 4.0 m

so we know that,

velocity ratio = $\frac{effortarm}{loadarm}$= $\frac{4}{0.3}$= 13.33

3. Conclusion:

Hence, the velocity ratio is 13.33.
