Amandla nokunwebeka

Ngokwemvelo, bonke oxhumene bese uxhumana njalo nomunye. ingxenye ngayinye, ingxenye ngayinye futhi isici is Njalo sibhekana lahlukene amabutho.

Naphezu kweqiniso lokuthi isibalo amabutho ngokwemvelo ngokwanele ezinkulu, bonke ngothi lwabo zingahlukaniswa zibe izinhlobo ezine:

1. ubunjalo amandla adonsela phansi.

2. ubunjalo amabutho kagesi.

3. Amandla yohlobo eqinile.

4. Amandla yohlobo ababuthakathaka.

amandla adonsela phansi kuyabonakala kuphela isikali bendawo yonke. kagesi imvelo amabutho - amabutho ezenzeka nokuxhumana izinhlayiya kokuba amacala athile kagesi.

amandla Nokunwebeka - lena bungamandla ezibaluleke kakhulu ngokwemvelo. Lapho yimuphi umzimba is phansi inqubo ukusonteka, ingaphakathi ke kukhona amandla ethile, okuyinto elilingana nebutho ka ukusonteka, kodwa uphawu obuhlukile. Amandla 'azithathe aqondiswe ngokumelene ukusonteka zomzimba. izinhlobonhlobo aso angamazinyo amandla eqine, phansi yokusabela force.

Ngo-physics, kukhona into okuthiwa ukusonteka nokunwebeka. ukusonteka Nokunwebeka - lo ukusonteka ngumkhuba lapho iphele ngemva amabutho angaphandle phezani ukwenza. Ngemva umzimba ukusonteka enjalo usunawo yayo yasekuqaleni. Ngakho, amandla nokunwebeka ncazelo uthi kwenzeka emzimbeni ngemva ukusonteka nokunwebeka ungamandla ezingaba khona. amandla Nekhono, noma amandla olandelanayo - ke ungamandla has umsebenzi walo ayikwazi kungancika ekutholakaleni trajectory yayo, kodwa kuphela endaweni yokuqala futhi ophela iphuzu phoqelela uhlelo lokusebenza. Sebenza amandla olandelanayo noma olandelanayo endleleni avaliwe zero.

Singasho ukuthi amandla nokunwebeka i nature kagesi. La mandla enza umzimba kungenziwa kulinganiselwa njengoba ukubonakaliswa macroscopic nokuxhumana phakathi amangqamuzana efana noma emzimbeni. Kunoma ikuphi lapho kukhona noma umzimba compressive noma eqine, sinezimfanelo amandla nokunwebeka. It is sibhekiswe amabutho esikhiqiza ukusonteka endaweni kolunye uhlangothi kuya displacement we izinhlayiya lomzimba perpendicular ukusonteka surface body kungokoqobo. Futhi, lolu Vector amandla iqondiswa kolunye uhlangothi kuya ukusonteka komzimba (ukufuduka zishintshe yayo).

Amanani ekubalweni amandla nokunwebeka eyenziwe ukusonteka emzimbeni, kwenzeka umthetho kaHooke. Ngokusho kwakhe, amandla entwasahlobo ilingana umkhiqizo ukuqina komzimba ukushintsha Coefficient ukusonteka zomzimba. Ngokomthetho kaHooke kwenzeka uma ukusonteka ethile yomzimba noma izidakamizwa nokunwebeka mandla ngqo wakhona ukunwebeka kwemisila umzimba, futhi iqondiswa ngendlela kolunye uhlangothi isiqondiso lapho izinhlayiya sishukumiseleka isihlobo ukuba lonke umzimba ngesikhathi kuyizinhlayiyana ukusonteka.

rigidity Inkomba umzimba ezithile noma Coefficient ezilinganiselwe incike ezisetshenziswa okwenza umzimba. Futhi ukuqina incike olinganise Jomethri futhi ukuma emzimbeni. Mayelana amandla nokunwebeka kukhona into okuthiwa i-ukucindezeleka mechanical. ukucindezeleka Unjalo isilinganiso kwamandla kuyaqina module per unit endaweni weyesi banikezwe kwesigaba enixoxa ngalo. Uma ujwayelana umthetho kaHooke lolu hlobo lokucindezeleka, kuyoba uzwakale okubekwe ngayo ukuhluka. Voltage uhlobo mechanical okuyinto eyenzeka emzimbeni ngesikhathi ukusonteka yayo, njalo wakhona ukunwebeka kwemisila umzimba. Kufanele kukhunjulwe ukuthi umphumela umthetho kaHooke kuphela engavimba deformations encane. Kukhona imikhawulo uhlobo umthetho usebenza ngaphansi kwayo. Uma uzobe kudlulwe, amandla nokunwebeka ibalwa amafomula ayinkimbinkimbi, kungakhathaliseki umthetho kaHooke.
