IV According to the table below, which of the following materials is the most brittle i.e. expands the least before breaking (4 points)? Youngs Modulus Ultimate Strength (10° N/m2) 400 50 170 50 Material (10 N/m2) Steel Wood Bone Glass 200 13 65 A. Steel B. Wood C. Bone D. CHass ultimate strenghth of both glass and wood is same but youngs modulus of wood is less as compared to glass so it will deformed more as compared to glass therefore most brittle material is glass
