Amandla xi

Ingcinezelo - lulwahlulo amandla leyo yenza perpendicularly kumphezulu ukuya kwindawo yalo umphezulu. iingcinezelo ulinganiswa Pascals (1 Pa - uxinzelelo yokuba amandla ka-1 newton kuvelisa kwi kwindawo yayo square metre esinye isicelo ngaphezulu).

Amandla nengcinezelo - ligunya kangangokuba kubeka uxinzelelo kwindawo ethile. It akalwa Newtons (N 1). Le ndawo umphezulu ezincinci, ephantsi koxinzelelo, incinci enokusetyenziswa force apho ziphumo zinqwenelekayo lungafezekiseka.

amandla xi enza phezu nkqo kuyo. Yinto ulinganiswa noxinizelelo. Ukuze ubone uxinzelelo eziyimfuneko ukumnyanzela ukuba nenxaxheba kobuso apho ibonakala. Ukuba sisebenzisa amandla afanayo ukwenza phezu ezohlukeneyo ngobukhulu, ingcinezelo uya kuba mkhulu apho kukho indawo zoqhagamshelwano ngaphantsi. Ukuba uyayazi indawo xi umphezulu, umkhosi xi ingafunyanwa phinda uxinzelelo kwi ndawo.

Le Amandla uxinzelelo yesiqhelo soloko ngokuyimfuneko wayalela aa Incopho kumphezulu apho unefuthe. Ngokutsho wesithathu umthetho Newton lilingana amandla emgangathweni asabela ngayo kwicandelo lakhe.

Indima amandla xi nako ukudlala nawaphi na amandla. Oku kunokuba ibe yimilinganiso leyo deforms inkxaso okanye amandla nokucofa nayiphi na umzimba ukuya kwindawo ethile, njalo-njalo.

Xa umfowunelwa kunye namaqumrhu okuqinileyo engamanzi benze nabo nomkhosi ethile, leyo ibizwa - amandla uxinzelelo. Kubomi bemihla ngemihla, ukuba uzive kumkhambo wokuba loo mandla njengoko kunokwenzeka, bagqume faucet umnwe umngxuma apho kufike amanzi. Ukuba ibhaloni yerabha kugalela mercury ukuze sibonwe ukuba iindonga zayo ziya uPienaar ngaphandle. Le Amandla uxinzelelo fluid banokuchaphazeleka nakuye kwezinye izinto ezimanzi.

Kokuqinileyo contact amandla elastic kuvela xa ukutshintsha imilo okanye umqulu. Xa ulwelo imikhosi ezinjalo xa ifom musa zenzeke. Ukungabikho luthambe malunga neenguqu imilo imisela ukuhamba iziselo. Xa ngokuveza kulwelo (ukutshintsha imiqulu yabo) ziya abonakalise amandla ilastiki. Yaba abo kuthiwa amandla koxinzelelo. Oko kukuthi, ukuba izenzo ulwelo kwi ukunxibelelana nabanye umzimba wakhe kunye ngamandla nengcinezelo, ngoko sikwimo zixinaniswe. Okukhona zixinaniswe ulwelo luqine iya kuvela ngenxa yabantu abasebenzayo loxinzelelo.

Ngenxa yoko, le ucinezelo kwandisa lexinene izinto, ke nolwelo ube misela esizibonakalisa ngokunxulumene mninzi zabo. Ukuba inqanawa yavalwa piston kunye nendawo phezu wolayisho, ulwelo uqala ukuyishwabanisa xa piston uvikivwa. Kuya kuvela amandla uxinzelelo leyo counterbalances ubunzima piston kunye umthwalo kubekwe phezu kwalo. Ukuba siqhubeka ukunyusa umthwalo piston, ulwelo iza kuqhubeka sofinyela, kunye nomkhosi njengoxinizelelo olwandayo ziya kujolisa silinganisa umthwalo.

Zonke ulwelo (ngaphezulu okanye ngaphantsi) unako zixinaniswe, ngoko ke kunokwenzeka ukulinganisa iqondo ucinezelo, ongqamana amandla ethile ingcinezelo.

Ukuba azole ukuhlisa uxinzelelo phezu kobuso, ukuba akunakwenzeka ukunciphisa amandla eziyimfuneko ukwandisa indawo yenkxaso. Kwelinye icala, ukuba andise uxinzelelo kuyimfuneko ukunciphisa indawo apho izenzo zakhe amandla.

I zegesi akadibananga (okanye lathamba kakhulu idityaniswe) phakathi ukusebenzisana amandla. Ngoko zihamba elingafani, phantse ngokukhululekileyo, ngokuzalisa yonke ivolyum isitya abayinikwe. Kulo mba, neempawu zerhasi yahluka ukusuka iimpawu iziselo. Xa mninzi igesi ixhomekeka uxinzelelo kangangoko enkulu kakhulu kunokuba ukuzala. A eqhelekileyo phakathi kwabo kukuba yengcinezelo ulwelo kunye negesi komntu akuxhomekekanga ekuzithandeleni imilo benqanawa leyo zingabekwa khona.
