Lift Chairs

Well, physiologically, women have a lower center of gravity than men, so, if a man and a woman, each places their back against the wall, faces a chair that is directly at their feet, and attempts to lift it without removing their buttocks from the wall, most men will find that they can't do it due to their higher center of gravity, but most women will find they can. It's simple body mechanics and no magic trick.

But it's not "science" that "girls can lift chairs better than guys." That's a bit too broad a statement.

If anything, it can equally be said that since men typically have more muscle mass than women, that in general, men can lift heavier objects.

Dentists' chairs are examples of hydraulic-lift systems. If a chair weighs 1700 N and rests on a piston with a cross-sectional area of 1260 cm2, what force must be applied to the smaller piston with a cross-sectional area of 72 cm2 to lift the chair?

____N
103.89 isn't right

f1 x a1 = f2 x a2
f2 = f1 x a1 /a2
=1760*1260 /72
calculate

Is it true that women can lift chairs easier than men because of their wide hips and something about lower mass gravity.

Does it have to be done while sitting down or standing up?

Does it sound like a good science experiment for my project?
Does this mean I have to use a very muscular boy and a very feminine girl for it?

Yep, you are right. For the most part, women have a lower center of gravity than men. (If you balanced people on a gym bar, men have a center of gravity around their belly button, while women's C.G. is a few inches lower. The usual "parlor trick" to demonstrate this is top ask men and women to stand one "foot length" from a wall then lean their head against the wall (please, have the boys use their arms...and not just fall into the wall with their heads...lol). For adults, most men can't stand up (lift their heads off the wall without using their arms; but women can). Exceptions: Very strong men with well developed abs and lower backs...just have them back up an extra inch or two...also girls who are built like boys will have trouble, too). I don't know if this by itself makes a good science experiment, but it might if you did some more comparisons of the body differences. Example, simulate a pregnancy with weights...most boys could not stand up...again, it's that C.G. thing. Compare lower and upper body strengths between boys and girls at different ages...most girls are faster and stronger than boys pre-puberty then it changes. That might make an interesting comparison of the mighty X vs puny Y chromosome, eh?

Hope this gets you thinking.

brand names of power lift chairs are Lazy boy, Golden

I don't see any either, but what you can do is go to sites like http://www.complaints.com and see if there are complaints on any of them

I did find a review on one: http://www.powerchair-review.fsnet.co.uk /ricon-powerchair-wheelchair-van-lifts.h tm
