Lbf vs Lbs
Pound mass lbm thiab phaus quab yuam lbf yog ob chav nyob rau hauv imperial system ntawm units. Lawv muaj feem cuam tshuam rau ib leeg thiab feem ntau tsis meej pem. Txawm hais tias nws tsis yog ib qho kev sib raug zoo ntawm cov chav nyob, muaj ntau qhov tsis zoo, imperial system ntawm units lossis ko taw-phaus-thib ob system ntawm units tseem siv.
lbs or lbm (Pound)
Pound yog chav tsev ntawm huab hwm coj nyob rau hauv imperial system (los yog f.p.s) system ntawm units thiab sib npaug rau 0.45359237 kilograms. Lub tsev yog muab los ntawm Roman system ntawm units. Muaj ntau qhov kev hloov pauv ntawm qhov tseeb ntawm ib phaus, tab sis Avoirdupois phaus raug suav tias yog tus qauv kev cai lij choj hauv ntiaj teb niaj hnub no. Nws yog ib qho tseem ceeb ntawm cov ko taw-phaus-thib ob qhov system.
Pound yog 16 ooj, thiab 1 slug yog 32.17405 lbm phaus.
lbf (Pound Force)
Pound force (lbf) yog chav tsev ntawm kev quab yuam hauv imperial systems ntawm units. Nws txhais tau tias yog lub zog xav tau los txhawm rau txhawm rau 1 slug loj (lossis 32.17405 lb m) ntawm tus nqi ntawm 1 ft / s. Qhov no tuaj yeem ua lej qhia raws li hauv qab no;
1 lbf =1 slug × 1 ft/s=32.17405 lbm × 1 ft/s
Kev sib raug zoo, feem ntau, yog Newton txoj cai thib ob. Txhawm rau tiv thaiv qhov tsis sib xws, qhov hloov pauv tau ntxiv rau qhov sib npaug ntawm Newton txoj cai thib ob.
pound force=C × pound mass × acceleration
Qhov twg 1/(32.17405) hloov cov phaus loj rau hauv slugs hauv qhov sib npaug. Lub zog phaus yog siv nyob rau hauv derived units xws li phaus taw, uas yog chav tsev ntawm kev ua hauj lwm nyob rau hauv lub f.p.s system.
Lbf thiab Lbs yog dab tsi?
• Lbs or lbm (Pound) yog ib chav tsev loj thaum Lbf (pound force) yog ib chav tsev ntawm lub zog hauv lub imperial system ntawm units.
• Pound force yog lub zog xav tau kom nrawm 1 slug mass (32.17405 lbm) ntawm tus nqi ntawm 1 ft/s.
