Insimbi ye-engeli egayiweinezinhlangothi ezimbili ezinobude obulinganayo, zakha isakhiwo se-engeli yesokudla esilingana kahle. Incazelo evamile, njenge-∠50×50×5, ikhombisa ukuthi izinhlangothi zombili zinobubanzi obungu-50 mm kanye nobukhulu obungu-5 mm. Ngenxa yesimo sayo esijwayelekile kanye nokusatshalaliswa kokucindezeleka okufanayo, ivame ukusetshenziswa ezakhiweni ezidinga ukuthwala umthwalo olingana kahle.

Umlenze ongalinganiibha ye-engeli ehlanganisiwe, njengoba igama lisho, inezinhlangothi ezimbili ezinobude obuhlukene. Isibonelo, u-∠100×80×8 umele uhlangothi olude olungama-100 mm, uhlangothi olufushane olungama-80 mm, kanye nobukhulu bodonga obungama-8 mm. Lo mklamo ongalingani uvumela ukuthi udlale indima eyingqayizivele ngisho nasezindlini ezingalingani noma ngaphansi kwemingcele ethile yendawo, okwenza kube lula ukusebenzisa izinto ngendlela efanele.

1. Ubude obuseceleni bensimbi ene-engile elinganayo buyafana; isibonelo, insimbi ene-engile engu-No. 4 evame ukusetshenziswa ibhekisela ensimbini ene-engile engu-40×40×4. I-"40x40" isho ukuthi izinhlangothi zombili zingama-40 mm; uma izinhlangothi zombili zinobude obufanayo, iyinsimbi ene-engile elinganayo; kanti insimbi ene-engile engafani inobude obuhlukile obuseceleni, kanti uhlangothi olulodwa lude kunolunye;
2. Imininingwane yensimbi ene-angle elinganayo isukela kuNombolo 2 kuya kuNombolo 20; imininingwane yensimbi ene-angle engafani isukela ku-∟50*32 kuya ku-∟200*125;
3. Insimbi engela elinganayo isetshenziswa kabanzi ezakhiweni zobunjiniyela ezifana namabhuloho, imibhoshongo yokudlulisa, imishini yokuphakamisa nezokuthutha, imikhumbi, kanye namashelufu okugcina impahla; insimbi engela engela engalingani isetshenziswa kabanzi ezakhiweni ezahlukene zezimboni zikamasipala, zomphakathi, zomphakathi, kanye nezempi, njengemishayo yokwakha yezimboni, izitofu zezimboni, imibhoshongo yokusabela, kanye nama-container racks. Njengoba isetshenziswa ngobuningi obuncane kunensimbi engela engela engalo eyodwa, intengo yayo iphakeme kakhulu.

1. Izinto ezisetshenziswa ngokulinganayoinsimbi ye-engelikanye nokungalinganiibha ye-engelikuyafana: insimbi ye-engeli ye-Q235B kanye nensimbi ye-engeli ye-Q345B;
2. Ubude obujwayelekile ngokuvamile buyi: insimbi engela engu-6m, insimbi engela engu-9m, kanye nensimbi engela engu-12m;
3. Indlela yokubala nayo iyafana: Isisindo ngemitha = 0.00785 * (Ububanzi becala + Ububanzi becala - Ubukhulu becala) * Ubukhulu becala.
