Which of the following is NOT a way that machines provide a mechanical advantage? a. change direction c. change power b. change distance d. change force

OpenStudy (amistre64):

hard to say .... which one of these does not fit in the definition of mechanical advantage?

OpenStudy (amistre64):

how does power relate to mechanical advantage?

see i was having a very hard time with this question,my teacher said it was change power but i got it wrong on my test so im lost...i dont know what to do

OpenStudy (amistre64):

mechanical advantage alters forces applied to forces generated ... my own vernacular of course. Power is the measure of the system as a whole, and is not dependant upon the parts of it. A ramp is a simple machine that makes it easier to move up. But the same amount of power is needed to move up 3 feet regardless of if you use a ramp or not.

OpenStudy (amistre64):

i might be mixing technical terms of work with power ... but i think the concept is sound :)

OpenStudy (amistre64):

The assumptions of an ideal machine are equivalent to the requirement that the machine does not store or dissipate energy, thus the power into the machine equals the power out. Therefore, the power P is constant through the machine and force times velocity into the machine equals the force times velocity out. from the wikipedia

okayee thanks @amistre64 ;)

OpenStudy (anonymous):

change in FORCE maybe??
