Sifunda ukuqhutshwa kwamagagasi

Izwe elisizungezile ligcwele ukuhamba. Kungenakwenzeka ukuthola okungenani umzimba owodwa ongokwenyama ongabhekwa njengokuphumula. Ngaphandle kokunyakaza okuqhubekayo okuqhubekayo okuhamba phambili, ukunyakaza okuhamba ngezinyathelo eziyinkimbinkimbi, ukunyakaza ngokusheshisa, nokunye okunjalo, singazibona ngamehlo ethu noma sithola ithonya lokunyakaza okuphindaphindiwe kwezinto ezibonakalayo.

Sekuyisikhathi eside umuntu ephawula izimpawu nezici ezihlukahlukene zokunyakaza okungahambisani nokufunda futhi wafunda nokusebenzisa ukukhishwa kwemishini ngenhloso yakhe. Zonke izinqubo eziphindaphinda ngokuhamba kwesikhathi zingabizwa ngokuthi yi-oscillations. Ukudlidliza kwamanzi kuyingxenye yalezi zenzakalo ezihlukahlukene ezivela emithethweni efanayo. Esikhathini esicacile sokunyakaza okuphindaphindiwe okuphindaphindiwe, kungenzeka ukuba wenze imithetho eyisisekelo futhi unqume imithetho lapho i-electromagnetic, electromechanical nezinye izinqubo ze-oscillatory zenzeka khona.

Imvelo yokubonakala kwezimoto ezisezingeni eliphezulu ikhona ekuguqulweni kwesikhashana kwamandla angaba amandla e-kinetic. Chaza isibonelo sokuthi ukuguqulwa kwamandla kwenzeka kanjani ngaphansi kwezidakamizwa eziyimishini, kungenzeka, ucabange ibhola elimisiwe entwasahlobo. Esimweni esithulile, amandla okugwedla amandla alinganiswa ukuqina kwetwasahlobo . Kodwa kudingekile ukucubungula uhlelo oluvela esimweni sokulingana ngokucindezela, ngaleyo ndlela kuphakamisa umkhondo ohlangothini lwephuzu lokulingana, njengoba amandla angase aqale ukuguqulwa kwawo abe yinkimbinkimbi. Futhi, futhi, kusukela ngesikhathi sokuhamba ibhola lesimo se-zero sizoqala ukuguqulwa sibe yinto enamandla. Le nqubo yenzeke uma nje izimo zokuba khona kwesistimu zisondela ezingenasici.

I-Mathematically ideal ibhekwa njengokungathi ukukhipha okwenzeka ngokuya komthetho we-sine noma i-cosine. Izinqubo ezinjalo ngokuvamile zibizwa ngokuthi ama-oscillation e-harmonic. Isibonelo esihle sezinkinobho ze-harmonic mechanical yisisindo se-pendulum endaweni engenawo umoya, lapho kungekho nethonya lamandla okubambisana. Kodwa lokhu kuyilungelo elingenasici, ukufezekisa ukuthi yikuphi okunzima ngempela.

Ukuchithwa kwemishini, naphezu kwesikhathi sabo, ngokushesha ukuyeka, futhi uhlelo luba nesimo sokulinganisela okulinganiselwe. Lokhu kubangelwa ukulahlekelwa kwamandla ukunqoba ukuphikiswa komoya, ukungqubuzana nezinye izinto eziholela ekushintsheni kwezibalo ekushintsheni kusukela ekuhle kuya kwezimo zangempela lapho uhlelo olubucayi lukhona.

Ngokungahambi ngokusondela ekutadisheni nokuhlaziywa okujulile, sifika isidingo sokuchaza ngezibalo ukushiya okwakhiwa. Amafomu kule nqubo ahlanganisa amanani anjenge-amplitude (A), i- frequency oscillation (w), isigaba sokuqala (a). Umsebenzi wokuxhomeka kwe-displacement (x) ngesikhathi (t) kwifomu yama-classic ifomu

I-X = I-Acos (wt + a).

Kufanelekile ukuphawula ukubaluleka kokuhlukanisa ama-mechanical oscillations, okubizwa ngokuthi isikhathi (T), esinqunywe ngezibalo

T = 2π / w.

Ukunyakaza kwama-mechanical, ngaphezu kokucacile kokuchaza izinqubo zokushintsha kwezinto ezingekho emthethweni, sithande ngezinto ezithile, lapho zisetshenziswe kahle, zingase zisebenzise kahle, futhi uma zinganakwa, ziholela enkingeni enkulu.

Ukuqaphelwa okukhethekile kufanele kukhokhwe kulokho okwenzekayo ekugxumeni okubukhali emakhulwini okugonywa okuphoqelekile okwenzeka lapho umvuthwandaba wesenzo sokushayela usondela kumvuthwandaba wokududuza kwemvelo komzimba. Ibizwa ngokuthi i-resonance. Esetshenziswe kakhulu kuma-elekthronikhi, ezinkambini zemishini, isimo se-resonance siyabhubhisa kakhulu, kufanele sicatshangelwe lapho sakha izakhiwo nezinhlelo eziningi ezihlukahlukene kakhulu.

Ukubonakaliswa okulandelayo kokudlidliza kwemishini kudlidliza. Ukubukeka kwalo kungase kungabangeli nje ukungahambi kahle, kodwa futhi kulethe i-resonance. Kodwa, ngaphezu komthelela omubi, ukudlidliza kwendawo ngendawo encane yokubonakalisa kungaba nomthelela omuhle emzimbeni womuntu wonke, kuthuthukiswe isimo somsebenzi wesistimu yezinzwa zomphakathi, futhi kufinyelele ngisho nokuphulukisa ukuphulukiswa kwamanxeba , njll.

Phakathi kwezinhlobonhlobo zokubonakaliswa kwezingcingo zomshini, umuntu angahlukanisa umphumela wezwi ne-ultrasound. Izakhiwo eziwusizo zala magagasi omsakazo kanye nezinye izibonakaliso zokungena kwemishini zisetshenziswa kabanzi emagatsheni ahlukahlukene kakhulu okuphila komuntu.
