Air ukumelana amandla - futhi ngaphandle nganoma iyiphi indlela

Thina zijwayele kangaka lihaqiwe emoyeni, okuyinto ngokuvamile bamshaya indiva kukho. Iphuzu lapha, ngaphezu kwakho konke, isicelo zezinkinga lobuchwepheshe, ikhambi okuyinto ekuqaleni ukhohlwe ukuthi kukhona amandla umoya ukumelana.

Isikhumbuza ngokwalo cishe noma yisiphi isenzo. Nakuba siyakuya ngemoto, nakuba flying indiza, ngisho noma thina nje ukujikijela itshe. Ngakho zama ukuqonda ukuthi yini amandla emoyeni ukumelana ngesibonelo amacala alula.

Ingabe wake wazibuza ukuthi kungani izimoto umumo ovikelekile futhi phezu flat? Kodwa-ke empeleni esicacile. Air ukumelana amandla yakhiwa ngobuningi ezimbili - ukumelana surface ngomshikisho lomzimba ukuma ukumelana umzimba. Ukuze kuncishiswe ibutho friction futhi sifinyelele ukuncishiswa of semfene maholoholo ezingxenyeni yangaphandle semoto yokukhiqiza kanye nanoma iziphi ezinye izimoto.

Ukuze wenze lokhu, basuke primed, sibe namabala, luze lacquered. workpieces okunjalo kuholela ekuphikeni yokuthi ukumelana air ayisukumele imoto kuyehla, ijubane imoto luyanda kanye petrol kuyehla uma ushayela. Ukuba khona amandla ukumelana ngenxa yokuthi uma imoto ihamba emoyeni onomfutho futhi ngaphambi kwakha endaweni endawo umfutho ophakeme, kulandele, ngokulandelana, endaweni cleaner.

Kufanele kuqashelwe ukuthi at ngesivinini umshini umnikelo main ngesimo ukumelana okwenza izimoto. Amandla ukumelana ukubala ifomula oboniswe ngezansi, lichaza izizathu abathembele kuzo.

Ukumelana Amandla = CX * S * V2 * r / 2

lapho S - ngaphambili kwelivi endaweni umshini;

CX - Coefficient ikhumbula emoyeni ukumelana;

V - Isivinini;

r - emoyeni kwabantu.

Njengoba kubonakala kalula kusukela ngenhla ifomula, ngamandla ukumelana akuxhomekile mass imoto. Umnikelo main wenziwe izingxenye ezimbili - i-kabili ijubane futhi ukuma imoto. okungukuthi ngokwandisa Isivinini kabili kane ukwandisa ukumelana. buka kahle cross-Sectional imoto has a elikhulu. Imoto kuyoba olandelanayo kakhulu, aphansi ukumelana emoyeni.

Futhi kule formula kukhona ipharamitha ukuthi umane Ufuna uyilethe ekuqapheleni - kwabantu emoyeni. Kodwa nomthelela waso isivele ngaphezulu liphinyiselwe ezindizeni. Kuyaziwa ukuthi nge kokuwa okwandisa kwabantu emoyeni incipha. Ngakho-ke ngeke yehlisa amandla yokumelana yakhe. ijubane futhi ifomu - kodwa lezi zici uzoqhubeka kuthinte indizamshini ukubaluleka ukumelana.

Ayikho ukwazi kancane umlando ekutadisheni emoyeni ithonya ukunemba. Imisebenzi yalolu hlobo kade kwenzeka, izincazelo lokuqala ezihlobene 1742. Ukuhlolwa Kwakuseshwa emazweni ahlukahlukene nge ukuma ezahlukene inhlamvu projectiles. Ngenxa yalokho zocwaningo ifomu kahle amachashazi wayezimisele kanye isilinganiso ikhanda nomsila yayo izingxenye etafuleni zenzelwe ballistic ichashazi ukuziphatha zindiza.

Kamuva yocwaningo olwenziwa ngokuvumelana inhlamvu ijubane layo uma igijima, ke waqhubeka ifomu wayekwenza inhlamvu, kanye ngcono izindlela zocwaningo. Sithuthukise onobuhle nezibalo Coefficient ballistic - ithuluzi ekhethekile zezibalo wadala. Ubonisa ratio sokunciphisa umoya lapho zindiza hudula amabutho kanye amabutho inertial ayisukumele inhlamvu.

Isihloko esichaza ukuthi amandla emoyeni ukumelana, ifomula kunikezwa okuvumela ukucacisa ubukhulu kanye nobungako kwethonya izici ezihlukahlukene ku ubukhulu ukumelana, umphumela walo kubhekwa emikhakheni ehlukahlukene ubuchwepheshe.
