Kungani umshini wokubonisa isivinini ukhombisa u-200 km / h nokuningi

I-speedometer yazo zonke izimoto zesimanje inesivinini esingu-200 km / h noma ngaphezulu. Umbuzo onengqondo uvela: kungani lokhu kudingekile, uma ukuthuthukiswa kwejubane elinjalo emigwaqweni ejwayelekile kusenqatshelwe? Ngaphezu kwalokho, imishini eminingi ayikwazi ukuphakamisa lokho kuphakama! Yini ukubamba?

Kukhona izimpendulo eziningana kulo mbuzo. Futhi ngayinye yazo ibaluleke kakhulu. Okokuqala okumele ukwazi ukuthi izimoto ezitholakalela abantu abajwayelekile zisengafinyelela isivinini esingu-200 km / h noma ngaphezulu. Bangakwenza (uma injini ivuma) kumathrekhi akhethekile. Njengesibonelo, eminye imigwaqo emikhulu eJalimane.

Iphuzu lesibili elibalulekile liphathelene nobuchwepheshe. Iqiniso ngukuthi lapho benza izimoto, onjiniyela bafuna inalidi ye-speedometer ingalokothi ishaye umkhawulo. Lokhu kuyadingeka ukuvimbela ukwehluleka kwemishini yolwazi. Vele, lokhu ikakhulukazi kuthinta izimo ezinamathrekhi afanayo, lapho imoto inelungelo lokusheshisa lifike kumakhilomitha angama-180 noma ngaphezulu ngehora.

Iphuzu lesithathu yinkinga ye-ergonomics. Ucwaningo oluningi lubonisa ukuthi kulula kakhulu ngomshayeli ukuthi abone ulwazi esikalini se-speedometer ezimeni lapho umcibisholo usenkabazweni yakhe yesobunxele noma eduze kwehora le-12 (maphakathi). Lesi sici sihlotshaniswa nemininingwane yobuchopho bomuntu kanye nokubona.

Ekugcineni, kukhona isici sesine - ukuhlanganisa. Izimoto zohlobo olufanayo zingahlonyiswa ngezinjini ezihluke kakhulu ngokwamandla. Ukuzihlomisa ngamadeshibhodi ahlukene, futhi nangaphezulu ngokudayela okuhlukile kwe-speedometer, kungaba udoti ohlangothini lomkhiqizi uma kuziwa ekukhiqizeni ngobuningi. Ngakho-ke, ama-speedometers anesivinini esingafinyeleleki nawo alula futhi alondoloza imali eningi kumamodeli wezimoto eziningi.
