Question

what should be the mechanical advantage of an Ideal machine? why ?​

Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction. It is always greater than the actual mechanical advantage because all machines must overcome friction.

Answer 2

Answer:

The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction. ... The mechanical advantage of a machine may be greater than, less than, or equal to 1, depending on the type of machine.

Explanation:

The ideal mechanical advantage is the mechanical advantage of a machine with no inefficiencies. ... The actual mechanical advantage is the ratio of the output force to the input force. The ideal mechanical advantage is the mechanical advantage in an ideal world. It equals the input distance divided by the output distance
