12.44 A three-point bending test is performed on a spinel (MgAl,O4) specimen having a rectangular cross section of height d = 3.8 mm (0.15 in.) and width b = 9 mm (0.35 in.); the distance between support points is 25 mm (1.0 in.). (a) Compute the flexural strength if the load at fracture is 350N (80 lb;). (b) The point of maximum deflection Ay occurs at the center of the specimen and is described by FL3 Ay = (12.11) 48EI where E is the modulus of elasticity and I is the cross-sectional moment of inertia. Compute Ay at a load of 310N (70 lb).
