Why Soap Bubbles Are Perfect!

[@turbopappi]

getting heaps of value from your super articulate bides is Paul, thank you so much!

[@anandjamdade9156]

Thank you Sir,you are geneous,I am engineer & from India & seeing your videos,teachers should be like you for engineering student who clear the basic concepts of engineering.

Interesting stuff! I hope you'll talk about this subject more in length. I'm an architecture major + structural engineering minor with in interest in organic forms. It seems as though the most efficient shape for tension is not always a sphere, is that correct? That under certain conditions, the optimal shape for the bubbles and, by extension, similarly designed tensile structures, might deviate from perfectly spherical geometry?

[@sran9492]

But there are some people usually in parks who put the string with a loop in it in soapy water and make very long bubbles how do you explain that, it still remains unbursted and has an opened end

Great question…Upcoming video!

Is the trick to structures spreading out the load and forces?

[@iamyou6555]

Hey Paul, was wondering if you can give a source for tension being the most materially efficient way to transfer force is it because it doesn’t lead to concentrated stress like bending or torsion?

[@kgosirantshilo2836]

I'm guessing it's cause it typically (I want to say always) doesn't produce secondary forces, with compression, u can get buckling and all that. Though you do get tension in things like bending, and I think torsion is just fancy tension but neither are induced by tension I think anyway

[@iamyou6555]

@ now that you mention it it’s a good point. Compression you can get secondary order effects from buckling which can create additional moments or crushing force. Do you want to connect? I like talk to people about interesting concepts
