1. ### Minimal Dimensions for Maximum Bending Moment

I realize the magnet will fly off if it is not secured properly. We need to assume that the magnet is secured onto the beam so that it will not come off. According to my lecturer, the minimum values for t and d that will resist bending must be solved for using: σ = Mc/I M = the...
2. ### Minimal Dimensions for Maximum Bending Moment

Thanks for the reply That's what I thought but when I spoke to my mechanics lecturer, he said that dynamic forces will not effect the bending of the beam because the dynamic forces will act along the beam towards the center axis. Therefore it is a static bending moment problem. How would...
3. ### Minimal Dimensions for Maximum Bending Moment

Hi Please can someone help me calculate the minimal thickness and width that will resist bending in each of the aluminium beams that are fixed on one end and support a 0.0013734 Newton load on the other. The axis passes through the center of the octagonal shape and goes into the page...
