Ib qhov loj tshaj plaws ntawm kev tsis meej pem hauv Imperial (los yog US Customary) system ntawm kev ntsuas yog ob qho tib si thiab quab yuam yog ntsuas siv tib lub tsev, phaus Qhov sib txawv ntawm ob, peb hu ib hom phaus pound-mass (lbm) thiab lwm yam phaus-force (lbf).
lbf sib npaug li cas?
Ib lbf, lossis ib phaus quab yuam, yog lub zog gravitational exerted los ntawm ib qho teeb meem ntawm lub ntiaj teb. … Hauv cov duab nws zoo li no, 1 lbm x 32.174049 ft/s2, los yog sib npaug rau 32.174049 ft. lbm/s2. Yog li yog tias peb hloov nws mus rau "N," lossis Newton, ces nws tsuas yog 1 lbf=0.45359237 kg x 9.80665m / s2=4.4482216152605 N.
Qhov txawv ntawm lbm thiab LBS yog dab tsi?
Pound mass, abbreviated lbm, yog ib chav tsev loj uas txhais tau tias yog 0.453 592 37 kilogram. Lub pound force unit, abbreviated lbf los yog yooj yim lb, yog ib chav tsev ntawm lub zog sib npaug rau qhov uas exerted los ntawm ib phaus loj nyob rau hauv lub gravitational acceleration ntawm lub ntiaj teb nto.
1 lbm hnyav li cas?
Raws li tus qauv ntiaj teb lub ntiajteb txawj nqus, 1 lbm hnyav 1 lbf thiab yog li ntawd lo lus "pound" feem ntau yog siv rau ob qho tib si loj thiab qhov hnyav hauv lus Askiv.
Koj yuav ua li cas hloov LBM rau lbf?
Kev hloov pauv ntawm Pounds-mass (lbm) thiab Pounds-force (lbf)
1. Siv Newton's 2nd Law (F=ma) kom pom qhov hnyav hauv lbm∙ft/s2. 2 2. Hloov qhov hnyav ntawm lbm∙ft/s2 rau lbf siv kev sib raug zoo 1 lbf=32.174 lbm∙ft/s2.
