The load-displacement record for a three-point bending test on alumina (A1203) ceramic is shown in the figure. The final fracture occurred at a force of 192 N and a displacement

of0.091 mm. With reference to Fig. 4.40(a) (book of Dowling), the distance between supports was L = 40 mm, and the cross-sectional dimensions were width t= 4.01mm and depth 2e=3.01 mm. Determine the following: the bend strength op (15 points) b) the ellastic modulus E. (15 points) c) discuss the differences between elastic modulus obtained in bending test and the one obtained in tensile test, (10 points)
