A three$-$point bending test was performed on an aluminum oxide specimen having a circular cross section of

radius $5\mathrm{.}0mm$; the specimen fractured at a load of $2660N$ when the distance between support points was $42$

$mm.$ Another test is to be performed on a specimen of this same material, but one that has a square cross

section of $11mm$ in length on each edge. At what load would you expect this specimen to fracture if the

support point separation is maintained at $42mm?$
