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;
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.
