Why Velocity Ratio Is Constant for a Machine?

Velocity ratio of simple machine is the ratio of distance travelled by the effort to the distance travelled by the load in the machine. As velocity ratio or ideal mechanical advantage is a simple ratio of two distances. Hence always remains constant.

Why does velocity ratio not change?

The ratio of input speed to the output speed is called the velocity ratio (VR) of a machine. For a given machine, the velocity ratio always remains constant and in ideal conditions, it will be equal to the mechanical advantage of the machine. The velocity ratio is a constant quantity.

Why velocity ratio is not affected by friction?

Explanation:because it is the ratio of distance, which is not affected by friction.
