Athree-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 6.7 mm; the specimen fractured at a load of 2710 n when the distance between support points was 41 mm. another test is to be performed on a specimen of this same material, but one that has a square cross section of 19 mm in length on each edge. at what load would you expect this specimen to fracture if the support point separation is maintained at 41 mm?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
