Txawb Steven los ntawm Brig
Caij nplooj ntoos hlav los mus ib txhis. Txog thaum nws xav mess ib ncig. Lub sijhawm no peb yuav ua tus qauv zoo heev los ntawm cov ntaub ntawv yooj yim. Cia peb rov ua qhov kev sim ntawm Stevin, uas tau tshawb pom qhov tshwm sim ntawm qhov sib npaug ntawm lub zog ntawm lub dav hlau inclined. Stevin Briga ntawm Flemish nyob rau hauv lub xyoo pua XNUMXth yog thawj tus tsim cov cuab yeej zoo li no. Cov lus xaus tau los ntawm qhov no muaj feem xyuam rau niaj hnub no. Cov ntawv ceeb toom tsis tau hais tias nws puas siv ntoo thiab duab los qhia rau kev tsim kho, zoo li peb tau ua. Txawm li cas los xij, nws txoj haujlwm tau los ua lub hauv paus pob zeb, uas yog, lub hauv paus ntawm niaj hnub statics.

Kev paub yog tias peb yuav tsim lub prism los ntawm daim duab peb sab. Cia peb tso lub prism horizontally ntawm lub tripod tshwj xeeb uas tsim rau lub hom phiaj no. Peb muab ib tug saw ntawm 14 zoo tib yam txuas rau ntawm prism. 2 txuas ntxiv rau ntawm thawj sab ntawm lub prism, 4 ntawm qhov thib ob, qhov seem 8 txuas txuas los ntawm hauv qab no, nyob rau sab thib peb raws qhov ntev. Lo lus nug yog, puas yuav sab saum toj ntawm 2 thiab 4 txuas cov saw hlau nyob hauv qhov sib npaug thiab ntev npaum li cas? Los yog tej zaum cov saw yuav pib tig ib ncig ntawm lub prism. Puas yog 4 qhov txuas yeej dhau 2 qhov txuas ntawm sab luv ntawm prism? Cia peb kawm txog peb tus kheej los ntawm kev tsim peb tus kheej qauv. Koj xav txog cov lus qhia ntawm koj cov npoj yaig lub ntsej muag thaum lawv pom cov saw maj mam tig mus ncig ntawm lub prism. Thiab koj tus kheej yuav muaj nuj nqis! Yog li, cia peb mus ua haujlwm tam sim ntawd.
cov ntaub ntawv ua qauv. Board rau lub hauv paus, rail, tuab cardboard thiab ib tug tiag tiag saw. Thaum kawg, peb xav tau chrome tshuaj pleev xim uas yuav muab lub xov tooj ntawm tes ua yeeb yam thiab ua haujlwm zoo.
Cov cuab yeej: ib tug laum, ib tug ntoo saw, sandpaper, hacksaw los yog ib tug thiaj li hu ua pob zeb diamond hlau txuas mus rau lub thav duab ntawm ib tug hacksaw es tsis txhob ntawm ib tug niaj zaus hniav, ib tug vise, ib tug kub kua nplaum rab phom, ib tug kav thiab ib daim duab los yog wallpaper riam, rau Piv txwv li, nrog cov hniav tawg.
Tripod: Cov cuab yeej ua raws li lub rooj tsavxwm ntsuas 140x110x12 millimeters lossis zoo sib xws. Lub hauv paus ntawm lub tripod yuav tsum muaj kev ruaj ntseg rau nws qhov hnyav thiab qhov loj me. Lub round ntsug hniav muaj qhov ntev ntawm 150 millimeters thiab txoj kab uas hla ntawm 7 millimeters. Nyob rau hauv lub hauv paus peb laum ib lub qhov nrog ib txoj kab uas hla sib npaug zos rau peb bar. Kaw ib lub strip ntawm cov kua nplaum kub los ntawm rab phom kub kua nplaum rau lub qhov no los ua ib lub tripod. Kab rov tav strip yog 70 mm ntev. Peb yuav txuas nws mus rau ib qho ntsug siv ib qho thaiv ntxiv ntsuas 30x30x30 millimeters nrog cov qhov drilled, raws li qhia hauv cov duab. Ib lub qhov yog drilled vertically, thiab lwm qhov yog perpendicular rau thawj. Txhua yam yog tuav hauv qhov chaw nrog cov kua nplaum kub. Thaum lub sij hawm gluing, peb yuav siv lub xwmfab kom lub kaum sab xis ntawm tus kheej cov txheej txheem. Ua ntej cov kua nplaum tau txias thiab khov kho, muaj lub sijhawm los kho lawv txoj haujlwm.
Rice. 1. Prism daim phiaj.
mobile tub ntxhais. Cia peb ua nws tawm ntawm cov ntawv tuab tuab. Peb yuav pib los ntawm kev kos duab trapezoid mesh. Cov kab tawg yuav tsum tau khoov, uas yuav ua rau nws yooj yim dua rau peb fold cardboard nyob rau hauv qhov chaw. Peb tuaj yeem khoov nrog tus cwj mem qub nrog rau qhov khoob khoob khoob. Lub pob spinning yuav precisely nias lub cardboard, tab sis yuav tsis ua puas nws. Cov duab los qhia tau yooj yim khoov ntawm lub quav thiab muab khi rau hauv qhov zoo nkauj prism nrog lub hauv paus peb sab. Thaum kawg, hauv ib lub hauv paus peb txiav ib lub qhov nrog ib txoj kab uas hla ntawm 7 millimeters.
kev teeb tsa. Mount lub prism nrog rau sab nrog lub qhov ntawm kab rov tav tripod caij smeared nrog kua nplaum los ntawm rab phom kua nplaum. Tom qab ib pliag, nws yuav lo khov kho thiab koj tuaj yeem pib pleev xim tus qauv nrog chrome varnish. Txij li thaum nws sov, pleev xim tuaj yeem ua rau sab nraud.
Kev kis tus kab mob nws yog tsim los ntawm ib daim ntawm saw. Thaum nws los txog rau ntawm txoj hlua, tsis txhob greedy tawm ntawm lub siab nyiam. Nws yog qhov zoo dua los yuav nws rau ib lub nyiaj hauv khw muag khoom kho vajtse. Peb xav tau tsuas yog kaum plaub kab txuas. Qhov ntev ntawm txhua qhov txuas yog 25 millimeters, thiab qhov dav yog 15. Qhov no yog qhov tseem ceeb, vim qhov seem ntawm cov qauv yog nyob ntawm qhov ntev ntawm qhov txuas. Siv lub hacksaw los yog pob zeb diamond xov, txiav ib qho ntawm cov saw txuas, ces qhib nws me ntsis thiab txuas cov saw rau hauv loops. Khoov qhov txuas txiav kom nws txawm thiab tsis muaj qhov sib txawv. Thaum peb tab tom soj ntsuam cov saw hlau, cov qauv pleev xim yuav tsum tau qhuav tawm thiab tsis hnov tsw phem heev. Thaum kawg, peb npaj ua si.
Lom zem: Tom qab muab cov saw tsav rau ntawm nws cov prismatic core, rub nws me ntsis mus rau sab xis kom peb cov saw hlau snaps rau hauv qhov chaw thiab thaum kawg pib txav mus. Cov kev sib txuas yuav tsum tau lubricated nrog graphite spray lubricant los yog tej zaum saw saw roj. Tom qab qee lub sijhawm, cov kev sib txuas maj mam swb hla saum npoo ntawm prism. Peb tuaj yeem pom nws hauv video.
Epilogue. Zoo heev. Ntawm chav kawm, lub mobile tsis txav. kuv tso dag. LUB XNUMX HLIS NTUJ Muaj tseeb tiag. Cov kev sib txuas ntawm cov saw txuas tsuas yog nyob rau hauv kev xav thiab yog qhov tseem ceeb hauv cov yeeb yaj kiab. Kuv paub koj hais mav tsis poob rau qhov no. Tau ntau pua xyoo, tshwj xeeb tshaj yog nyob rau Nruab Nrab Hnub nyoog, tib neeg sim ua tsis tiav los tsim cov khoom siv zoo li no thiab zoo sib xws. Thaum kawg, cov kws tshawb fawb tau tshawb pom txoj cai ntawm kev txuag hluav taws xob. Yog li, lawv tuaj mus rau qhov xaus tias nws yog tsis yooj yim sua kom ua ib tug perpetual motion tshuab, i.e. ib qho cuab yeej uas, tsis tau kos lub zog los ntawm txhua qhov chaw, yuav txav mus los, thiab ua qee yam haujlwm. Hmoov zoo, tsawg thiab tsawg tus neeg tsis ntseeg qhov tseeb no.
Hauv lwm qhov kev sim, Stevin nrhiav tau lwm txoj cai tseem ceeb ntawm kev siv tshuab. Ob qho kev sib txuas sib txuas sib npaug sib npaug ntawm ob lub dav hlau inclined thaum lawv qhov hnyav yog proportional rau qhov ntev ntawm qhov chaw siab tshaj. Cia peb tawm ntawm ib leeg tus pej thuam ntawm mechanics ntawm lub cev thaum so, peb cov qauv nyiaj. Ua kom zoo dua ntawm huab cua zoo nkauj, koj tuaj yeem taug kev tus dev, coj mus rau hauv tus account qhov teeb meem ntawm perpetual motion tshuab raws txoj kev, uas yog twv yuav raug hu tsis yooj yim sua. Kuv txhais tau tias, nws tuaj yeem ua tau, tab sis nws yeej yuav tsis ua haujlwm.
