Nokuba umtsha kumbhobho okanye kwishishini lombhobho wealloy okanye ubukwishishini iminyaka, igama elithi "Shedyuli 40" alinto intsha kuwe.Ayilogama nje elilula, sisitshixo semetric, ke makhe simbe nzulu kwaye sifumanise ukuba kutheni iShedyuli yama-40 ithandwa kangaka!
Yintoni iShedyuli 40
Umbhobho weShedyuli ye-40 ngumbhobho onobunzima obuthile bodonga.Ubukhulu bodonga oluthile buya kuhluka ngokuxhomekeke kububanzi bangaphandle bombhobho.Oku kungenxa yokuba inombolo emva kweShedyuli ayibhekiseli ngokuthe ngqo kubukhulu bodonga oluthile, kodwa kukwahlulahlula.
Ifomula yokubala inombolo yeShedyuli yindlela elula yokuqikelela ubudlelwane phakathi kobunzima bodonga lombhobho kunye noxinzelelo oluphantsi kwayo.
Ifomula yile ilandelayo:
Inombolo yeShedyuli = 1000 (P/S)
Pimele uxinzelelo olusebenzayo loyilo lombhobho, ngokuqhelekileyo kwi-psi (iiponti nge-intshi nganye yesikwere)
Simele uxinzelelo oluncinci oluvumelekileyo lwezinto zombhobho kwiqondo lokushisa lokusebenza, kwakhona kwi-psi (iipounds nge-intshi yesikwere).
Le fomyula ibonelela ngesakhelo sethiyori sokuqonda ubudlelwane phakathi kobunzima beemibhobho ezinamaxabiso ahlukeneyo eShedyuli kunye noxinzelelo oluphezulu abanokumelana ngokukhuselekileyo.Ekusebenzeni, ixabiso leShedyuli lombhobho lichazwe kwangaphambili kumgangatho.

Ukuqina
Imibhobho yeShedyuli ye-40 inika ukhuseleko olugqwesileyo lomatshini kunye nokumelana nokugqwala ngenxa yobukhulu bodonga olumodareyithayo, okwenza ukuba kusebenze ixesha elide kwiindawo ezahlukeneyo.
Ukuthotyelwa kweMigangatho
IShedyuli ye-40 yepayipi ilandela imigangatho eyaziwayo ngamazwe afana ne-American Society for Testing and Materials (ASTM) kunye ne-American Society of Mechanical Engineers (ASME) ukuqinisekisa umgangatho kunye nokusebenza kwayo.
Ukufumaneka lula
Ngenxa yokusetyenziswa kwayo ngokubanzi, imibhobho yeShedyuli ye-40 ifumaneka kakhulu kwimarike kwaye ithengwa ngokulula kwiindidi ezahlukeneyo zobukhulu kunye nezixhobo.
Uhlalutyo olunzulu lweShedyuli ye-40 imibhobho lubonisa ukuba banikezela ibhalansi efanelekileyo ngokweendleko, amandla, ukuqina, kunye nokuguquguquka kwesicelo.Oku akukwenzi nje ukuba ibe yinxalenye ebalulekileyo yoluhlu olubanzi lweeprojekthi.Njengoko ukuqhubela phambili kweteknoloji kunye nemigangatho ihlaziywa rhoqo, iShedyuli ye-40 imibhobho ngokungathandabuzekiyo iya kuqhubeka isetyenziswa ngokubanzi kwihlabathi jikelele ukuxhasa ukwakhiwa kweziseko ezingundoqo kunye nophuhliso lwemizi-mveliso.
