Question

mechanical advantage is the ratio of *​

Answer 1

Answer:

Mechanical advantage, also called force ratio, is the ratio of the output force (load) of a machine to the input force (effort). In the case of an ideal (frictionless and weightless) machine, mechanical advantage = velocity ratio.

Answer 2

Answer: $M.A.=\frac{F_{o} }{F_{i} }$

Step-by-step explanation:

• Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
• The formulae to measure the mechanical advantage is force output divided by force input.
• $M.A.=\frac{F_{o} }{F_{i} }$ where $F_{o}$ is the Force output and $F_{i}$ is the Force input.

• Hence,the mechanical advantage is the ratio of force output and the force input.
