Faa'iidooyinka Tuubada Birta Ductile
Ductility ka weyn birta la shubay
Iska caabin saameyn oo ka weyn birta la shubay
Awood ka weyn birta la shubay
Ka fudud oo ka sahlan in la dhigo marka loo eego birta la shubay
Fududeynta kala-goysyada
Kala-goysyadu waxay qaadi karaan qaar ka mid ah leexashada xagasha
Kharashyada bamgareynta oo hooseeya sababtoo ah dhexroorka gudaha ee weyn
