Qhov siab tshaj plaws shear stress yog sib npaug rau ib nrab ntawm qhov sib txawv ntawm tus thawj tswj hwm kev ntxhov siab. Nws yuav tsum raug sau tseg tias qhov sib npaug ntawm cov dav hlau tseem ceeb, 2θp, yields ob lub kaum sab xis ntawm 0 ° thiab 360 °.
Yuav ua li cas yog lub mis rau siab tshaj shear stress?
Txoj kev nyuaj siab tshaj plaws yog nyob ntawm 45o dav hlau thiab sib npaug σx / 2.
txhais li cas los ntawm qhov siab tshaj plaws shear?
Qhov siab tshaj plaws shear stress yog qhov siab tshaj plaws siab shear quab yuam nyob rau hauv ib cheeb tsam me. … Qhov nruab nrab axis ntawm ib tug ntoo khaub lig seem yog lub axis uas tus nqi ntawm cov kev ntxhov siab ib txwm thiab strain yog sib npaug rau xoom.
Qhov siab tshaj plaws shear stress nyob rau hauv lub beam nyob qhov twg?
Qhov siab tshaj plaws shear stress tshwm sim ntawm qhov nruab nrab axis thiab yog xoom ntawm ob sab saum toj thiab hauv qab ntawm lub nqaj. Shear flow muaj units ntawm quab yuam ib chav nyob deb.
Unit ntawm shear force yog dab tsi?
Lub cev qhov ntau ntawm kev ntxhov siab yog ntsuas hauv lub zog faib los ntawm cheeb tsam. Hauv SI, chav tsev yog pascal (Pa) lossis newtons ib square meter. Hauv Teb Chaws Asmeskas kev cai units, shear stress kuj feem ntau ntsuas hauv phaus-force ib square inch lossis kilopounds-force ib square inch.
