Do you think I could just leave this part blank and it'd be okay? We're just going to replace the whole thing with a header image anyway, right?

Question 3 [5 marks]
Your objective is to minimize the weight, cost and environmental impact of the beam. Derive an
expression for the mass of your beam in terms of the yield strength, density and other parameters.
Show all working. From this, generate a Material Index that you can use to minimise the mass of
the beam. To simplify calculations, when deriving the performance indexes, approximate b=t and
eliminate the cross-sectional area as the “free” variable (even though your final dimension may not
be a square cross-section).
From this equation, give similar equations for the total cost and total embodied energy (Hint: these
will look very similar, but will include factors for cost/kg and EE/kg).
State the slope of the design guidelines that should be used to optimise your selection.

Oh! Sorry! Sorry, sorry! I hope I didn't disturb you too much, then. Um, I'm listening to some uh, classical music. This one is by, um--what's his name? Wolfgang...uh, Wolfgang Beethoven. Who--my personal favorite, if I'm honest. Um, I just love all the--I just love all the bloody melodies! That he comes up with. Hummable, they are. That's--to me, that is the mark of great music, if you can hum along. And I can, to this one, on all of them. So I'm not a moron."
