Nilai wiwitan sing disaranake
Petungan torsi ing ngisor iki mung ditawakake minangka pandhuan. Panganggone isine dening sapa wae dadi tanggung jawabe wong kasebut lan dheweke tanggung jawab kabeh.
Amarga akeh variabel sing mengaruhi hubungan torsi-tensi kaya kesalahan manungsa, tekstur permukaan, lan pelumasan, siji-sijine cara kanggo nemtokake torsi sing bener yaiku liwat eksperimen ing kahanan sendi lan perakitan sing nyata..
