Into ebizwa mzuzu amandla? Indlela ukuchaza ngayo?

Makhe sibone oko kuthiwa ingongoma amandla. Eli gama lisetyenziswa kumaxesha physics. Kuhlalutywa phantsi kwe binzana ithetha ukuba umsebenzi emagxeni kwaye ziqhotyoshelwe wempi yakhe.

iimpawu

Ukuhlalutya umbuzo okubizwa ngokuba mzuzu amandla kuyimfuneko ukukhankanya kunye neeyunithi eli xabiso. Kwinkqubo SI oko ulinganiswa NM.

torque

Torque amandla malunga nqanaba ixabiso ezinxulumene ulawulo oluxhathisayo kwaye namandla. Kubomi bemihla ngemihla, abantu badla sebenzisa "lever rule", esisusela ngqo kwi ndawo amandla.

Ngokomzekelo, ukuze kulungiswe umonakalo-ujingi, sifanele sazi oko kuthiwa mzuzu amandla, kwaye ukuba ii kakuhle. Gxalaba ebizwa ithuba lokuphumla phakathi kwindawo isicelo nencopho pivot.

Umzekelo, kunzima ukuvula ucango, ngokulityhala kwakhona ukusuka amanqaku obandayo. Ukuze siqonde ukuba kutheni le nto kunzima kangaka ukuba wenze, kufuneka uyazi into ibizwa ngokuba mzuzu yakwenza malunga esqwini.

Masithi kufuneka uvule ucango, ukuba imitha ububanzi, annexing 100 N. Ukusebenzisa kufuneka kwiindawo ezintathu:

• kufuphi kwiihenjisi;
• kwi ziko;
• e enyeleni ngelaphu.

Kuba nomlenze icala lokuqala zero, ngenxa yoko, umsebenzi kwi ingalo iya bafakela ixabiso amandla zero.

Ngokuba ukhetho embindini emnyango, mzuzu liya kunxibelelana 50 NM. Emzantsini kwindawo ucango igqabi liya kuba xabiso liphezulu 100 NM.

izibalo ezinje zenza kube lula ukucinga ukuba ilahleko umgama ihlawulelwa kukho inzuzo kwi umgudu.

nomlenze wasekunene

Kwimeko isicelo umkhosi kwi-engile, akunakwenzeka ukuba bathethe malunga ekugqibeni imikhosi zamagxa njengoko kubhekwe ngaphambili. Ukumelana nalo msebenzi, kufuneka usebenzise nomlenze wasekunene. imikhosi Gxalaba ebizwa ubude nkqo ukuba ishiyiwe ukusuka kwindawo pivot kumgca we yintshukumo amandla.

Ukuze kumiselwe amandla ngengalo, ukuze bandise umda. Emva koko uvikivwa nkqo ukusuka kwindawo pivot.

Isiphumo unxantathu engile. Ukusebenzisa imithetho kwitrigonometri, kunokwenzeka ngenxa sinus ukufumanisa mzuzu amandla.

Ukucinga ukuba mandla isicelo kwi-engile degrees 45. Kulo mzekelo, ixesha ifunyenwe 70 NM. Kuyacaca ukuba isebenze ukuvula ucango kwi-engile 0 degrees. Loo mandla akanayo uqikelelo ezinokudala intshukumo ejikelezayo. Ukungabikho emagxeni akhe, ngaphandle zero, akavumeli amandla ukudala torque. Xa sicinga nto ibizwa ngokuba mzuzu zigalo, kufanele kuqatshelwe ukuba kukho inani yomzobo yesiboniso. Ukuze kumiselwe ulwalathiso mzuzu zigalo, sebenzisa ulawulo ekunene-ngesandla. Ngokufanayo, babone icala kumda wesangqa Velocity emboxo.

Yintoni ekhethekileyo ngale mthetho? Gquma entendeni esqwini ngesandla sokunene ujikelezo, kangangokuba kolwalathiso iminwe kungqinelane ulwalathiso amandla isicelo. Nasesithupheni amisele ulwalathiso emboxo isantya kumda wesangqa amandla. Yintoni ibizwa ngokuba mzuzu yakwenza malunga ingongoma elimisiweyo? Eli xabiso, leyo inxulumanisa ezayo ngomzuzu kumda wesangqa amandla kunye axis malunga apho yokubala iza kwenziwa.

Ingongoma ephambili amandla na kumda wesangqa yona udibaniso onke mathuba yomntu ngamnye imikhosi ukuba senze inkqubo ngokuphathelele kwindawo efanayo. iziko lakhe call ukuba yonke inkqubo yomkhosi.

Xa lwalo jikelele, isiphumo amanyathelo kuyo nayiphi na inkqubo eqinileyo iyafana yintshukumo torque kwenkqubo engundoqo kwakunye kumda wesangqa imikhosi izicelo kwiziko yokuhambisa.

isiphelo

Ukuze ufumane inkcazelo torque isicelo umthetho esisiseko zentshukumo, leyo oluphawula sawa ejikelezayo. Uthi lo mzuzu inertia, ukukhawulezisa emboxo, torque. Emva kaArchimedes wasungula kwengalo yasekunene, ngaphandle utshintshwano iye isetyenziswe phantse 1,900 eminyaka. Kuphela kwisiqingatha sesibini sisazinzulu French kwinkulungwane ye-17 P. Pierre Varignon oko yatshintshwa kwaye ngenxa nemikhosi torque.

Ukuba azisebenzisele yena zilingana, ukulingana M1 = M2. Torque luphawu amandla ojikelezayo amanyathelo. Kuxhomekeke nje kuphela amandla kodwa egxalabeni lakhe. Ukuze ukhulule nut, sebenzisa utsalo elide. Ngezikhonkwane ngokukhawuleza basonta screwdriver ukuba igqityezelwe ngesiphatho ngokwaneleyo elide.
