(a) A three-point transverse bending test
is conducted on a cylindrical specimen of
aluminum oxide having a reported flexural
strength of 390 MPa (56,600 psi). If the
specimen radius is 2.5 mm (0.10 in.) and
the support point separation distance is 30
mm (1.2 in.), predict whether you would
expect the specimen to fracture when a
load of 620 N (140 lbf) is applied. Justify your prediction.
