Lub tshuab kuaj thoob ntiaj teb yog lub tshuab kuaj cov khoom siv uas sib xyaw ua ke ntawm tensile, dabtsi yog khoov, compression, shear, thiab lub nplhaib nruj kev sim ua haujlwm. Nws yog tsuas yog siv rau kev ntsuam xyuas cov khoom siv hlau thiab tsis yog -cov ntaub ntawv hlau thiab yog cov khoom siv ntsuas zoo tshaj plaws rau kev lag luam thiab kev lag luam mining, cov tsev tshawb fawb, cov tsev kawm qib siab, thiab cov chaw saib xyuas engineering zoo.
Lub tshuab ntsuas universal yog lub tshuab kuaj tshuab muaj peev xwm ua tau ntau yam kev sim xws li nro, compression, dabtsi yog khoov, thiab torsion. Feem ntau hom yog qib -hom thiab hydraulic- hom.
