(17 pts) 10) A three-point bending test is performed on a glass specimen having a rectangular cross section of height d=5 mm and width b= 10 mm; the distance between support points is 45 mm. a) Compute the flexural strength if the load at fracture is 290 N. (9 pts) b) The point of maximum deflection Ay occurs at the center of the specimen and is described by FL³ Ay = 48EI where E is the modulus of elasticity (69 GPa for glass) and I is the cross-sectional moment of inertia. Compute Ay at a load of 266 N. (8 pts)
