Q2. (a) In order to calculate the maximum stress in bending, section modulus S firstly need to be determined. A larger section modulus in structural section results in lower maximum stress due to the bending. i. ii. = Define the section moment of inertia for I shape in Figure 2.1 when h h=b and bb. (8 marks) Using your answer in Q2 (a) i., determine the section modulus S of the shape when h = 30 cm. h X I b h b Figure 2.1 Cross-sectional of I-beam. h (2 marks) Q2.
