Nyob rau hauv qhov sib npaug torsion lub sij hawm J/R hu ua shear modulus section m.

qhov sib npaug torsion txhais li cas?

Torsion equation lossis torsion tas li txhais tau tias yog cov cuab yeej geometrical ntawm ib qho kev hla ntu uas koom nrog hauv axis ntawm lub bar uas muaj kev sib raug zoo ntawm lub kaum sab xis ntawm kev sib tw thiab siv lub zog uas nws chav tsev SI yog m 4^{. Qhov sib npaug torsion yog muab raws li hauv qab no:} TJ=τr=GΘL.

Koj ua li cas rau qhov sib npaug torsion?

1. (Gθ/L)J (hloov rau lub caij nyoog polar ntawm inertia)
2. ∴ T/J=τ/r=Gθ/L.
3. Cov no yog cov kauj ruam ua raws kom tau txais qhov sib npaug torsion. …
4. Twisting Moment:

Kev sib luag torsion ntshiab yog dab tsi?

General torsion equation

T=torque or twisting moment , [N×m, lb×in] J=polar moment of inertia or polar second moment of cheeb tsam txog ncej axis, [m⁴, in^{4] τ=shear stress at outer fiber, [Pa, psi] r=radius of the ncej, [m, in}

lub zog torsional yog dab tsi?

ntsuas lub peev xwm ntawm cov khoom siv los tiv thaiv kev sib tw. Nws yog qhov kawg ntawm lub zog ntawm cov khoom uas raug torsional loading, thiab yog qhov siab tshaj plaws torsional kev nyuaj siab uas cov khoom txhawb nqa ua ntej rupture.
