Q.5 Two wooden planks ISO mm x 50 mm each arc connected to form a T-section of a beam. If a moment of 3.4 kNm is applied around the horizontal neutral axis, inducing tension below the neutral axis, tlnd the stresses at the extreme fibres of the cross-scction. Also calculate the total tensile force on the cross-section. (5)
