Question

difference between velocity ratio and mechanical advantage​

Answer 1

Answer:

Mechanical Advantage is the amount the force is multiplied by the machine. It depends on the design of the machine, and also losses to friction etc. ... Velocity Ratio is how much faster the input force moves than the output force.

Answer 2

$\huge\purple{\bf{\underline{Question:-}}}$

Difference between velocity ratio and mechanical advantage.

$\huge\pink{\bf{\underline{Answer:-}}}$

As velocity ratio or ideal mechanical advantage is a simple ratio of two distances, it also does not have the unit. The friction is not involved in it. The efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (input work).

Mechanical advantage is defined as the ratio of resistance overcomes to the effort applied. Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine.
