Amandla selastiki

Kwindalo, bonke oqhagamshelwano phakathi kwaye basebenzisane gqolo kunye nabanye. inxalenye nganye, icandelo ngalinye elementi uhlala kuboniswa iintlobo lonke imikhosi.

Nangona inani emvelo mkhulu ngokwaneleyo, yonke nguwuphi na kubo zohlulwa ngokwendidi ezine:

1. uhlobo amandla omxhuzulane.

2. uhlobo amandla kagesi.

3. Amandla uhlobo olunamandla.

4. Mandla lohlobo ibuthathaka.

amandla omxhuzulane zibonakala ngokucacileyo kuphela isikali yonke. emvelo magnetic - imikhosi ukuba kwenzeka impefumlelwano amasuntswana ukuba izityholo ezithile zombane.

amandla selastiki - le yenye yezona imikhosi ibalulekileyo kwindalo. Xa umzimba phantsi inkqubo deformation, ngaphakathi kwayo kukho amandla ethile, nto leyo ilingana amandla deformation, kodwa uphawu esahlukileyo. Umkhosi luvela ngqo nxamnye deformation umzimba. iintlobo awo amandla saluqilima, umgangatho reaction amandla.

Physics, kukho ikho into deformation ilastiki. deformation selastiki - le deformation yi esenzeka ngayo liyalahleka emva imikhosi yangaphandle ayeke ukwenza. Emva umzimba deformation ithatha imilo yayo yoqobo. Ngenxa yoko, amandla elastic nkcazelo ithi ukuba kwenzeka emzimbeni emva kokuba deformation elastic Kungenzeka amandla. amandla agciniweyo, okanye amandla endala - kungamandla eye umsebenzi wayo akakwazi kuxhomekeka indlela yayo, kodwa kuphela indawo uhambo oluqala noluphela kuyo isicelo amandla. Sebenza amandla endala okanye endala ahambe ngendlela evaliweyo ngu zero.

Sinokuthi ukuba amandla elastic zohlobo electromagnetic. ukuyiqikelela Le mandla njengoko kubonakaliswa kokukhulu yentsebenziswano phakathi molecule iziyobisi okanye emzimbeni. Kuyo nayiphi na imeko apho kukho mhlawumbi umzimba compressive okanye eqine, ukuthi kuziveza ungamandla elastic. It sibhekiswe imikhosi ezivelisa deformation kwicala malunga ukubana abantu amasuntswana lomzimba nkqo ukuya deformation kumphezulu mzimba usisisulu. Kwakhona, le esiyua mandla sibhekiswe kwelinye icala ukuya deformation omzimba (ukubana of iimolekyuli zayo).

Iinqobo ekubaleni amandla elastic eyenziwe deformation emzimbeni, kwenzeka umthetho Hooke kaThixo. Ngokutsho kwakhe, umkhosi emthonjeni ilingana imveliso ngumkhinkqi lomzimba ukutshintsha ukungavumelani kwe deformation komzimba. Ngokutsho komthetho Hooke lenzeka xa deformation elithile lomzimba okanye iziyobisi ilastiki mandla kisekiyo ngqo zobude lomzimba, yaye wayalela kwicala malunga indlela apho amasuntswana azamazama kuthelekiswa wonke umzimba ngexesha isuntswana deformation.

index nokoma umzimba ethile okanye lomlingani umlinganiselo luxhomekeke umbandela kusetyenziswa ukuvelisa umzimba. Kwakhona ukuqina kuxhomekeke olinganise zejometri kunye nokumila komzimba. Ngokumalunga amandla elastic kukho into efana a xi ngoomatshini. uxinezeleko okunjalo umlinganiselo amandla imodyuli okubuyela kwimo nganye unit indawo kwindawo elinikiweyo kwicandelo phantsi ingqalelo. Ukuba unxulumana umthetho Hooke eli ucinezelekile, oko kuya kuvakala amagama eyahlukileyo kancinci. Ombane Uhlobo mechanical okwenzeka emzimbeni ngexesha deformation wayo, usoloko ngokomlinganiselo zobude komzimba. Mayisoloko ikhunjulwa into yokuba ifuthe umthetho Hooke bakaThixo umda kuphela deformations ezincinane. Kukho imida ubunzima isebenza phantsi apho komthetho. Ukuba uya kugqithiswa, amandla elastic libalwa ifomula ezintsonkothileyo, nokuba umthetho Hooke kaThixo.
