Je, ni fomula gani ya kipenyo cha chini cha shimoni chini ya mzigo wa mzunguko?

For a solid circular shaft: d = ∛(16T/(πτ_all)), where T is the applied torque and τ_all is the allowable shear stress. This comes from the torsion formula τ = Tc/J = 16T/(πd³) for a solid shaft.

Je, ninachaguaje msongo wa kukatika unaoruhusiwa?

The allowable shear stress is typically 50-60% of the tensile yield strength: τ_all = 0.577 × σ_y (von Mises criterion). For steel AISI 1045: τ_all ≈ 180 MPa. Apply a safety factor of 1.5-3.0 depending on application criticality and loading type.

Je, shimoni tupu inalingananaje na shimoni imara?

A hollow shaft with the same outer diameter has slightly less torsional strength but much less weight. The strength ratio is (1-k⁴) where k = d_i/d_o. For k = 0.5 (ID = half OD), you retain 93.75% of strength at about 75% of the weight.

Je, ninapaswa kuzingatia makato ya ufunguo na mkusanyiko wa msongo?

Ndiyo. Nyufa za ufunguo hupunguza nguvu ya mhimili kwa asilimia 25-50 kulingana na aina. Tumia sababu ya mkusanyiko wa msongo Kt (kawaida 1.6-3.0 kwa nyufa za ufunguo). Msongo wa ufanisi unakuwa τ_eff = Kt × τ. Pima ukubwa wa mhimili kwa msongo uliokusanyika au punguza msongo unaoruhusiwa ipasavyo.

Je, kuhusu kuchanganya kuinamika na msokoto?

When both bending moment M and torque T act, use the equivalent torque: T_eq = √(M² + T²) for maximum shear stress theory, or T_eq = √(M² + 0.75T²) for von Mises criterion. Then size the shaft using T_eq in place of T.
