what formula should i use to calculate the shaft diameter according to the load due to bending and torsion??
Bending loads refer to forces that cause a bending or flexing of the shaft, while torsion loads refer to forces that cause twisting or rotation of the shaft.
The maximum bending stress on a shaft can be calculated using the bending moment equation, σ = (M * c) / I, where σ is the maximum stress, M is the bending moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia of the cross-sectional area of the shaft.
The required diameter of a shaft for bending and torsion loads is affected by the material properties of the shaft, the magnitude and direction of the loads applied, and the desired safety factor.
The maximum shear stress on a shaft can be calculated using the shear stress equation, τ = (T * r) / J, where τ is the shear stress, T is the applied torque, r is the radius of the shaft, and J is the polar moment of inertia of the cross-sectional area of the shaft.
The safety factor for shaft design is the ratio of the maximum stress the shaft can withstand to the maximum stress it is expected to experience. A higher safety factor indicates a more robust and reliable design.
