Sharaxaada Alaabta
Mid ka mid ah faa'iidooyinka ugu muhiimsan ee tuubooyinkeena birta ah waa codsigeeda qalabka farsamada iyo tuubooyinka warshadaha.Xooggooda dabacsanaan iyo qallafsanaaneed ee aad u wanaagsan, tuubooyinkeena ayaa dammaanad qaadaya waxqabadka ugu wanaagsan ee deegaannadan baahida badan.Intaa waxaa dheer, naqshadeeda khafiifka ah waxay hubisaa in si sahlan loo maareeyo loona rakibo, badbaadinta waqti iyo kheyraad qiimo leh.
Tuubooyinkeena birta-la'aanta ah kuma koobna codsiyada warshadaha laakiin waxaa si weyn loogu isticmaalaa qaybo dhisme iyo farsamooyin kala duwan.Xooggeeda aan la dabooli karin iyo adkeysigeeda ayaa ka dhigaya doorasho lama huraan u ah soo saarista qaybaha farsamada iyo qaab-dhismeedka injineernimada.Laga soo bilaabo mashaariicda dhismaha ilaa wax soo saarka baabuurta, dhuunteenna birta ah waxay bixisaa aasaas adag oo hal-abuurnimo iyo korriin.
Isticmaalka warshadaha iyo makaanikada ka sokow, tuubooyinkeena birta-la'aanta ah waxay helayaan dariiqa ay u galaan alaabta guriga iyo warshadaha qalabka jikada.Iyaga oo nadiif ah, muuqaal jilicsan, waxay ku daraan taabashada xarrago meel kasta.Laga soo bilaabo godadka kuraasta adag iyo miisaska ilaa saxanka jikada ee waara iyo maacuunta, tuubooyinkeena birta ah ee aan kala go'a lahayn ayaa ah doorasho badan oo loogu talagalay codsiyada ganacsiga iyo deegaanka.
