I have a 1/k scale model of a weight on a tripod (http://gosper.org/legbox3.jpg). Alan Adler tells me beam strength scales with the width and the square of the thickness, so k^3.

What happened to the cube in d = 4Fl^3/(Yab^3) d = displacement F = force l = length of the beam a = width of beam b = thickness of beam Y = Young’s modulus Or have I misunderstood the question?
