Question

According to the definition of Velocity Ratio (V.R.),

• A. load distance and effort distance both have to be same all the time.
• B. it is a ratio of effort distance to a load distance.
• C. it is a ratio of a load distance to an effort distance.
• D. an effort distance has to be small to have a larger velocity ratio.

Answer 1

The correct option is B

it is a ratio of effort distance to a load distance.

The definition of Velocity Ratio(V.R) relates distance through which an effort acts and because of it, how much distance load moves. Or in other words, it is the ratio of a distance through which any part of a machine (an effort) moves to that which the load moves during the same time.
