Cov compressive kev nyuaj siab formula yog: CS = F÷ A, qhov twg CS yog tus lub zog khov , F yog quab yuam los yog thauj khoom ntawm qhov tsis ua tiav thiab A yog qhov chaw hla ntu ntu ntu.
Ib yam nkaus, koj yuav xam lub zog quab yuam li cas?
Compressive Kev nyuaj siab Cov mis Cov qauv rau xam compressive kev nyuaj siab yog yooj yim. Nws suav los ntawm kev faib cov quab yuam thov los ntawm cheeb tsam nws yog siv rau. Qhov no qauv tom qab ntawd tau siv los nkag siab tias cov khoom siv yuav coj zoo li cas hauv kev nyuaj siab nws xav tias yuav nyob qis.
Tsis tas li ntawd, yuav ua li cas koj xam compressive zog ntawm ib tug load? Compressive zog test Cov compressive zog yog xam los ntawm kev siv lub sib npaug , F = P/A --------- 1 Qhov twg, F = Lub zog loj ntawm qhov hnoos qeev (hauv MPa). P = tau Qhov siab tshaj plaws load siv rau qhov hnoos qeev (inN).
Yog li ntawd, lub zog ntawm compression yog dab tsi?
Compression quab yuam (los yog compressive quab yuam ) tshwm sim thaum lub cev quab yuam nias sab hauv ntawm ib yam khoom, ua rau nws dhau los ua kev cog lus. Hauv cov txheej txheem no, qhov txheeb ze ntawm atom thiab molecules ntawm cov khoom hloov pauv.
Dab tsi yog tensile thiab compressive quab yuam?
Kev nyuaj siab sawv cev rau kev ua ntawm a quab yuam los yog momenton ib tug qauv. Yog hais tias tus quab yuam rub tus tswv cuab (nruj) nws ua rau a tensile kev nyuaj siab; yog tias quab yuam thawb tus tswv cuab ( compression ) nws ua rau hauv compressive kev nyuaj siab. Tensile stresses stretch ib memberand ceev stresses nyem ib tug tswv cuab.

Dab tsi yog daim duab qhia kev quab yuam?
Daim duab qhia lub zog yog siv los txheeb xyuas cov kev tawm tsam no thiab teeb tsa theem rau kev hloov pauv tau. Kev hloov pauv yuav tsis tshwm sim thaum lub zog tsav tsheb thiab kev txwv tsis pub muaj kev sib npaug, lossis cov kev txwv tsis pub muaj zog tshaj qhov tsav tsheb
Yexus txhais li cas los ntawm Coj kuv tus quab rau koj?
Ua raws li tus Tswv txhais tau hais tias peb txais Nws cov lus rau Nws cov thwj tim: “Cia li los cuag kuv, cov uas ua hauj lwm thiab ris nra hnyav, thiab kuv yuav pub koj so. Coj kuv tus quab rau ntawm koj thiab kawm los ntawm kuv, vim kuv muaj siab mos siab muag thiab txo hwj chim; thiab koj yuav pom kev so rau koj tus kheej
