Bold text How are inclined planes useful?Read below

From the article:

"The inclined plane is used to reduce the force necessary to overcome the force of gravity when elevating or lowering a heavy object. The ramp makes it easier to move a physical body vertically by extending the distance traveled horizontally (run) to achieve the desired elevation change (rise)."

=> This means that if you are not strong enough to lift an object straight up, you can overcome this with a ramp; with a ramp you can lift the object using a smaller force, at the cost of having to lift it a longer distance. I think this article needs some language and explanatory cleanup. Do you think this should be better explained in the article?

[edit] Example problem

I've started cleaning up the example physics problem. I don't have time to do it all now, but I think it needs to be tightened up significantly. flowersofnight (talk) 20:56, 14 June 2006 (UTC)

[edit] Audio Recording

(edited)I changed my mind, re-reading this it seems like it needs some more work...It looks like the inclined plane and the wedge have been confused (not that they are all that different anyway).

This entire article has been copied and pasted from this site: http://www.weirdrichard.com/inclined.htm

Surely someone had just pasted it on without citing it... —The preceding unsigned comment was added by 74.116.163.147 (talk) 22:06, 18 March 2007 (UTC).

Well I think that site should be fined!! Don't you?

[edit] [incorrect mechanical advantage statement]

before I changed it, the article read that the IMA of an inclined plane can also be expressed as the sine of the angle between the slope and horizontal plane. This is wrong, because the IMA is the hypoteneuse over the height, not the other way around.

I have changed it to read the ratio of 1 to the sine of that angle described above to make it correct

[edit] Energy expenditure

"Many devices based on the principle of the inclined plane allow expending less individual energy to achieve a task."

I believe this is incorrect. At best, an inclinded plane requires expending exactly the same amount of energy when used to increase the elevation of a weight, hence the expression . In reality, where loss due to some sort of friction is unavoidable, an inclinded plane may actually require more energy to raise a weight than simply lifting it outright. -AndrewDressel (talk) 13:55, 21 May 2008 (UTC)
