Question

A simple machine has velocity ratio 3, what did you mean​

Answer 1

Answer:

A simple machine having a velocity ratio of 3 simply means that the ratio of the distance moved by effort to the distance moved by load is equal to 3.

Explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;

I. Inclined plane.

II. Screw.

III. Wheel and axle.

IV. Lever.

V. Wedge.

VI. Pulley.

Mathematically, the velocity ratio of a simple machine is given by the formula;

$Velocity \; ratio = \frac {Distance \; moved \; by \; effort}{Distance \; moved \; by \; load}$

Hence, a simple machine having a velocity ratio of 3 simply means that the ratio of the distance moved by effort to the distance moved by load is equal to 3.
