I would think that mild steel and cast iron would be, possibly tool steel? And the rest I don't think they do. Unfortunately I don't have any magnets.

So the ferrous metals I think are Stainless steel, cast iron, mild steel, tool steel and HSLA steel. Are these all attracted to a magnet?

So the formula for stress = load/area is not needed for this?

How do you go about determining the maximum working load? Is it 470 Mpa?

What does the 'safety factor of 3' do in terms of this equation? So the formula stress= load/area is not needed to calculate maximum working tensile load? The area of the shaft is 9.5^2 x π = 283.52

I have been given this question by my teacher as part of a quiz and I'm confused on how to start. 1. Calculate the maximum working tensile load that a 19mm shaft is able to take with a safety factor of 3. Material UTS 470 Mpa 2. Stress = load/area When it states 'area' what is this the are of...

1. I would like to test myself on how well I know my information about certain metals, some of them get me a bit puzzled. How would you rate the electrical conductivity of cast iron? Poor, good, excellent or best? Also the thermal conductivity of 304 stainless steel? Poor, good, excellent or...
