Steel tables for calculating axle diameter

[Wilson123]

Ah yes, I forgot to convert to MPa.

I am familiar with deflection however not sure how to calculate it under these parameters, could you give me some pointers?

Just to be clear on one point - Is there another extension and load at the other end of the axle ?

 

[Wilson123]

No there isn't, my design has one axle per wheel, so the other wheel is supported by a mirror image of this axle.

After looking over my calculations, I've realized I had my bending moment slightly too high, therefore my bending stress is wrong. My bending stress is actually 63MPa.

Do you still want any help with this problem ?

@JBA has kindly provided this reference to formulas for stress and deflection in another thread . You can use these formulas for your problem as well .
