I have a steel grade of material thickness 0.62 mm. I want to know how to calculate equivalent thickness of Aluminium which will have the same strength as that of the steel. Can I do that by using Ultimate Tensile Strength of both the materials. Please clarify.

Thanks

I want to get a phase converter to convert single phase 240 to three-phase. There are two types. A static phase converter uses capacitors and electronics and a rotary phase converter uses an idler motor with capacitors and some circuitry. Where my brother-in-law works they use a phase converter and he says it produces a very loud, high pitched whine. I don't want that. Which converter is the loud one? It sounds to me like the rotary phase converter is the better product in terms of the waveforms it produces, but is it also quiet?
I need a phase converter that can deliver 3 Hp.

When a smooth clean aluminum disc is pulled out from distilled water at a constant and slow speed, water droplets formed on disc surface. The water droplet formation is due to the adhesive force between water and aluminum surface is stronger than the water molecules itself. What can I do to reduce or to eliminate water droplet formation on the aluminum surface?
