Question

Explain how the ideal mechanical advantage and efficiency of a machine determine the machine’s actual mechanical advantage.

Answer 1

what part of it don't u get?!
Imagine u have a machine that has a mechanical ideal advantage of 1.. which means if u put a force of 100N, u get a force of 100 N..
and lets say the actual machine is only 80% efficient..

tell me when what will this machines output be.. ? if u input 200N of force?!

Answer 2

2N.

Answer 3

:O... tell me how did u get that?! this machine has 80 percent efficiency and a mechanical advantage of 1.. and u put in 200N of force!

Answer 4

Then idk how i would get it..-_-

Answer 5

ok.. imagine.. that.. the efficiency was 100 percent.. and mechanical advantage of 1.. then what would bet eh output?

Answer 6

It is 2 .

Answer 7

nope.. u don't understand the concept of mechanical advantage do you!?

if mechanical advantage is n, then the output force is n times the input

so if it is 5... then the output force would be 5 times more than in the input force.. do u understand what m saying?!

Answer 8

Ok maybe i should ask for some extra help on that..Thanks

Answer 9

hmmm.. its really easy.. its what i said..
so a machine wiht 10 mech advantage.. would give u 10 times more than input force..

then put in the efficiency.. !

Answer 10

Your force is multiplied by the mechanical advantage times its efficiency. If MA is 10 and efficiency is 75% then your force is multiplied by (0.75)(10) = 7.5.
