Shear Stress hauv Shafts

  1. Shear Stress nyob rau hauv ib qho khoom Ncej Equation .
  2. Thaum torque los yog twisitn loading yog siv rau lub cylindrical ncej , a shearing kev nyuaj siab yog siv rau lub ncej .
  3. Cov shear stress nyob rau hauv ib qho khoom cylindrical ncej nyob rau ntawm qhov chaw muab:
  4. σ = T r / Ip
  5. Qhib: Shear Stress nyob rau hauv ib qho khoom Ncej Calculator .
  6. Qhov twg.
  7. σ = shear stress (MPa, psi)

Tom qab ntawd, tus ncej torque suav li cas?

Raws li txoj cai, peb tuaj yeem siv cov qauv hauv qab no,

  1. Torque = Force * perpendicular nrug (los ntawm qhov chaw axis mus rau qhov taw tes ntawm kev quab yuam)
  2. Lub zog = (2 * pi * N * T) / 60.

Ib tug kuj yuav nug, dab tsi yog lub mis rau torsion? General torsion kab zauv T = lub zog los yog twisting moment, [N×m, lb×in] J = polar moment of inertia los polar second moment of area about ncej axis, [m4, hauv4] τ = shear stress at outer fiber, [Pa, psi] r = radius of the ncej, [m, in]

Ntawm no, qhov twg qhov siab tshaj plaws shear stress nyob rau hauv ib ncig ncej vim torsion?

Thaum a ncej yog raug a lub zog los yog twisting a shearing kev nyuaj siab yog tsim nyob rau hauv lub ncej . Cov shear stress Nws txawv ntawm xoom hauv axis mus rau a siab kawg nyob rau sab nraud ntawm lub ncej . "Polar Moment of Inertia ntawm Ib Cheeb Tsam" yog ib qho kev ntsuas ntawm a ncej muaj peev xwm tiv taus torsion.

Dab tsi yog shear stress formula?

Cov qauv rau shear stress yog tau = F / A, qhov twg 'F' yog lub zog siv rau ntawm tus tswv cuab, thiab 'A' yog qhov chaw hla ntawm tus tswv cuab.
