Question 5: (a) A three-point bending test is conducted on an aluminum oxide ceramic with a circular cross section. The ceramic has a radius of 4 mm. The specimen fractures at a load of 1100 N as measured by an Instron universal tester. If the distance between the supports was set to 5 cm, what would be the flexural strength of the ceramic
