Power seat motor problem??

Q: tom lawrence wrote note in order to not go off on all kinds of wild tangents im deliberately ignoring the factor of acceleration here... for our purposes all objects being discussed are assumed to be at a constant speed... could be zero could be mach5 - but were not going to introduce acceleration into the mix here.... things are complicated enough you cant ignore acceleration. thats what g is after all! that mass of helium not volume remember.. weighs 11.25lbs. here on earth. in a vacuum yea but we dont live in a vacuum. how much does it weigh out in the open as both a liquid and a gass sigh 11.25lbs. tom.... pressure does not change the mass of a gas only its volume. therefore since mass is constant and so is gravity hang on again..... thunk.... yep still constant it weighs the same. yes because then it has a weight positive downward force. no... it has greater density than its surrounding gas... has nothing to do with weight. it still weighs the same. go back to the ice cube example.... why does an ice cube float in a glass of water is it weightless does gravity somehow stop acting on it because you put it in the glass why does the weight of that glass increase when you plop an ice cube in it its the exact same principle youre continuing ot argue and its absolutely rediculous. i think theres some confusion over mass and volume and density. a ship would be pretty heavy yet it generally floats on water. not because its lighter than the water but because it weighs less than the volume of water it displaces. same for a hot air balloon. the ice cube and water example is a bit more complicated since water has a rather unusual property it gets more dense as it cools like most stuff but then just as it approaches freezing it suddenly gets less dense! very unusual but fortunate if you are a fish since otherwise rivers would freeze up in winter from the bottom up! there goes the ice fishing season! smh .

ok steve what would you put on your truck to protect it from stone chips like you got to have mud flaps so you have to drill a couple of holes to install them right. how about protecting the wheel well lips. do you leave the metal bare and use touch up the paint once in awhile for any chips im asking these questions because im going to get it painted and not putting anything back on. i have the mopar running boards they are ok and they are mounted to the underside. they help prevent damage to the rocker panel. fmb suggested xliner will look into that. dale ditto on the rhino lining. several trucks at the local 4x4 jamboree have had it sprayed on rockers wheel wells or complete underside of body and it looks good and lasts forever. denny .
