Umjaho webhola
Kulokhu ngiphakamisa ukuthi wenze idivayisi elula kodwa ephumelelayo yekilasi le-physics. Kuzoba umjaho webhola. Enye inzuzo yomklamo wethrekhi ukuthi ilenga odongeni ngaphandle kokuthatha indawo enkulu futhi ihlale ilungele ukukhombisa isipiliyoni somjaho. Amabhola amathathu aqala kanyekanye ukusuka emaphuzwini atholakala endaweni yobude obufanayo. Imoto eklanywe ngokukhethekile izosisiza ngalokhu. Amabhola azogijima ngezindlela ezintathu ezahlukene.
Idivayisi ibukeka njengebhodi elilenga odongeni. Amashubhu amathathu asobala anamathiselwe ebhodini, izindlela lapho amabhola azohamba khona. Umugqa wokuqala mfushane kakhulu futhi unomumo wendiza evamile ethambekele. Eyesibili ingxenye yesiyingi. Ibhendi yesithathu isesimweni socezu lwe-cycloid. Wonke umuntu uyazi ukuthi umbuthano uyini, kodwa akazi ukuthi ubukeka kanjani nokuthi i-cycloid ivelaphi. Ake ngikukhumbuze ukuthi i-cycloid iyijika elidwetshwa iphuzu eligxilile eduze kwendingilizi, igingqa ngomugqa oqondile ngaphandle kokushelela.
Ake sithi sibeka ichashazi elimhlophe ethayini lebhayisikili bese sicela othile ukuthi aphushe ibhayisikili noma aligibele kancane emugqeni oqondile, kodwa okwamanje sizobheka ukunyakaza kwechashazi. Indlela yephoyinti enamathiselwe ebhasini izozungeza i-cycloid. Awudingi ukwenza lokhu kuhlola, ngoba emfanekisweni singabona kakade i-cycloid ehlelwe kumephu nayo yonke imizila ehloselwe ukuthi amabhola agijime. Ukuze senze kahle lapho siqala khona, sizokwakha isiqalisi se-lever esilula esizoqala womathathu amabhola ngokulinganayo. Ngokudonsa i-lever, amabhola ashaya umgwaqo ngesikhathi esifanayo.
Ngokuvamile intuition yethu isitshela ukuthi ibhola elilandela indlela eqondile kakhulu, okungukuthi, indiza ethambekele, iyoba esheshayo futhi iwine. Kodwa i-physics noma ukuphila akulula kangako. Zibonele wena ngokuhlanganisa le divayisi yokuhlola. Ozosebenza. Izinto zokwakha. Ucezu lweplywood elingunxande olulinganisa amamilimitha angu-600 ngo-400 noma ibhodi likakhokho lobukhulu obufanayo noma obungaphansi kwamamitha amabili wepayipi lepulasitiki elisobala elinobubanzi obungamamilimitha angu-10, ishidi le-aluminium elingu-1 millimeter obukhulu, ucingo olungamamilimitha angu-2 ububanzi. , amabhola amathathu afanayo okumele ahambe ngokukhululeka ngaphakathi kwamashubhu. Ungasebenzisa amabhola ensimbi athwele aphukile, isibhamu somthofu, noma amabhola esibhamu, kuye ngobubanzi bangaphakathi bepayipi lakho. Sizolenga idivayisi yethu odongeni futhi kulokhu sidinga izibambi ezimbili esingalengisa kuzo izithombe. Ungathenga noma wenze izibambo zocingo ngezandla zakho kithi.
amathuluzi. Isaha, ummese obukhali, isibhamu seglue esishisayo, i-drill, i-sheet metal cutter, amapliers, ipensela, i-puncher, i-drill, ifayela lezinkuni kanye ne-dremel okwenza umsebenzi ube lula kakhulu. Isisekelo. Ephepheni, sizodweba izindlela zokuhamba ezintathu ezibikezelwe ngesilinganiso esingu-1: 1 ngokomdwebo osencwadini yethu. Esokuqala siqondile. Ingxenye yesiyingi sesibili. Umzila wesithathu ngama-cycloids. Siyakubona esithombeni. Umdwebo olungile wamathrekhi udinga ukudwetshwa kabusha ebhodini lesisekelo, ukuze kamuva sazi ukuthi singanamathisela kuphi amapayipi azoba amathrekhi amabhola.
Imigwaqo yebhola. Amashubhu epulasitiki kufanele abe obala, ungabona ukuthi amabhola ethu ahamba kanjani kuwo. Amashubhu epulasitiki ashibhile futhi kulula ukuwathola esitolo. Sizosika ubude obudingekayo bamapayipi, cishe amamilimitha angu-600, bese siwafinyeza kancane, afanele futhi azame kuphrojekthi yakho.
Landelela usekelo lokuqala. Ebhodini lezinkuni elilinganisa amamilimitha angu-80x140x15, bhoboza izimbobo ezintathu ngobubanzi bamashubhu. Imbobo esinamathela kuyo ithrekhi yokuqala, i.e. okubonisa ukulingana, kufanele kugawulwe futhi kwenziwe njengoba kukhonjisiwe esithombeni. Iqiniso liwukuthi ithubhu ayigobi nge-engeli efanele futhi ithinta ukuma kwendiza ngangokunokwenzeka. I-tube ngokwayo iphinde isikwe nge-engeli eyakhayo. Namathisela amashubhu afanele kuzo zonke lezi zimbobo kubhulokhi.
umshini wokulayisha. Kusuka ephepheni le-aluminium 1 mm ubukhulu, sinquma ama-rectangles amabili ngobukhulu, njengoba kuboniswe emdwebeni. Kweyokuqala neyesibili, sibhoboza izimbobo ezintathu ezinobubanzi obungamamilimitha ayi-7 nge-coaxially ngokuhlelwa okufanayo njengoba izimbobo zabhojwa emgqeni wokhuni owakha ukuqala kwamathrekhi. Lezi zimbobo kuzoba izidleke zokuqala zamabhola. Gcoba izimbobo epuletini lesibili elinobubanzi obungamamilimitha ayi-12. Namathisela izingcezu ezincane ezingunxande zeshidi lensimbi emaphethelweni adlulele epuleti elingezansi futhi nakuzo zepuleti eliphezulu elinezimbobo ezincane. Ake sinakekele ukuqondanisa kwalezi zakhi. I-centre plate engu-45 x 60 mm kufanele ilingane phakathi kwamapuleti aphezulu naphansi futhi ikwazi ukushelela ukuze ivale futhi ivule izimbobo. Ama-plaque amancane ananyathiselwe phansi nangaphezulu azokhawulela ukunyakaza kwe-lateral plate emaphakathi ukuze ihambe kwesokunxele nakwesokudla ngokuhamba kwe-lever. Sifaka umgodi kule plate, ebonakalayo emdwebeni, lapho i-lever izofakwa khona.
ingalo ye-lever. Sizoyigoba ocingweni olunobubanzi obungamamilimitha ama-2. Ucingo lungatholakala kalula ngokusika ubude obuyi-150 mm kusuka ku-hanger yocingo. Ngokuvamile sithola i-hanger enjalo kanye nezingubo ezihlanzekile kusukela ekugezeni, futhi iba umthombo omuhle kakhulu wocingo oluqondile nolugqinsi ngezinjongo zethu. Gobisa ingxenye eyodwa yocingo nge-engeli engakwesokudla ebangeni elingamamilimitha ayi-15. Esinye isiphetho singavikelwa ngokubeka isibambo sokhuni kuso.
Ukusekelwa kwe-Lever. Yenziwe ngebhulokhi enobude obungamamilimitha angama-30x30x35 ukuphakama. Phakathi nendawo ye-block, sibhoboza imbobo eyimpumputhe enobubanzi obungamamilimitha angu-2, lapho ichopho le-lever lizosebenza khona. Qeda. Ekugcineni, kufanele ngandlela thize sibambe amabhola. Isibungu ngasinye siphetha ngokubamba. Ayadingeka ukuze singabheki amabhola agcwele igumbi ngemuva kwesigaba ngasinye somdlalo. Sizokwenza ukuthwebula kusuka kucezu lwepayipi elingu-50 mm. Ngakolunye uhlangothi, sika ishubhu nge-engeli ukuze udale udonga olude lapho ibhola elizolishaya ukuze uqedele umzila. Ngakolunye uhlangothi lwe-tube, sika i-slot lapho sizobeka khona i-valve plate. Ipuleti ngeke livumele ibhola ukuthi lingalawuleki ndawana thize. Ngakolunye uhlangothi, lapho nje sikhipha ipuleti, ibhola ngokwalo lizowela ezandleni zethu.
Ikhweza idivayisi. Ekhoneni eliphezulu kwesokudla sebhodi, ekuqaleni okumakiwe kwawo wonke amathrekhi, namathisela ibhulokhi yethu yokhuni lapho sinamathisele khona amashubhu esisekelweni. Namathisela amashubhu ngeglue eshisayo ebhodini ngokwemigqa edwetshiwe. Indlela ye-cycloidal eqhelile ukusuka phezulu kwe-slab isekelwa ngobude bayo obumaphakathi ngebha yokhuni engu-35 mm ukuphakama.
Namathisela amapuleti embobo kwibhulokhi yokusekela yethrekhi ephezulu ukuze angene emigodini yebhulokhi yokhuni ngaphandle kwephutha. Sifaka i-lever emgodini wepuleti ephakathi kanye neyodwa ku-casing yomshini wokuqala. Sifaka ukuphela kwe-lever enqoleni futhi manje singakwazi ukumaka indawo lapho inqola kufanele ifakwe ebhodini. Umshini kufanele usebenze ngendlela yokuthi lapho i-lever iphendukela kwesokunxele, zonke izimbobo ziyavuleka. Maka indawo etholakele ngepensela futhi ekugcineni unamathisele ukusekela ngeglue eshisayo.
Okujabulisayo. Silenga ithrekhi yomjaho futhi ngesikhathi esifanayo idivayisi yesayensi odongeni. Amabhola anesisindo esifanayo nobubanzi abekwe ezindaweni zawo zokuqala. Vula i-trigger ngakwesobunxele futhi amabhola azoqala ukuhamba ngesikhathi esifanayo. Ingabe besicabanga ukuthi ibhola elisheshayo entanjeni kuzoba yileli elikuthrekhi emfushane ka-500mm? Ingqondo yethu isihlulekile. Lapha akunjalo. Ungowesithathu entanjeni. Ngokumangalisayo, kuyiqiniso.
Ibhola elisheshayo yilelo elihamba endleleni ye-cycloidal, nakuba indlela yayo ingamamilimitha angu-550, kanti elinye yilona elihamba engxenyeni yesiyingi. Kwenzeka kanjani ukuthi ekuqaleni kwawo wonke amabhola abe nejubane elifanayo? Kuwo wonke amabhola, umehluko ofanayo wamandla ongaba khona uguqulelwe amandla e-kinetic. Isayensi izositshela ukuthi umehluko wezikhathi zokuqeda uvelaphi.
Uchaza lokhu kuziphatha kwamabhola ngezizathu eziguqukayo. Amabhola angaphansi kwamandla athile, abizwa ngokuthi amandla okusabela, asebenza emabhola asuka eceleni kwamathrekhi. Ingxenye evundlile yamandla okusabela, ngokwesilinganiso, inkulu ku-cycloid. Iphinde ibangele ukusheshisa okumaphakathi okumaphakathi kwalelo bhola. Kuyiqiniso elingokwesayensi ukuthi kuwo wonke amajika axhuma noma yimaphi amaphuzu amabili omjuluko wamandla adonsela phansi, isikhathi sokuwa se-cycloid sifushane kakhulu. Ungaxoxa ngalo mbuzo othakazelisayo kwesinye sezifundo ze-physics. Mhlawumbe lokhu kuzobeka eceleni elinye lamakhasi amabi.
