Question

Define Actual Mechanical Advantages with reference to a machine?

Answer 1

Mechanical advantage

Mechanical advantage literally means advantage given by the machine, in terms of effort applied, and load lifted by it.

Mechanical advantage is classified into two classes

1. Ideal mechanical advantage
2. Actual mechanical advantage

Actual mechanical Advantage

The ratio between useful load moved to the effort applied is called actual mechanical advantage.

$AME=\frac{l}{E}$

‘I’ is the useful load

'E' is the effort.
