Question 2. W2 I h W The figure (not drawn to scale) shows the cross-section of a wooden beam made of nailed planks and subjected to the vertical shear force V. Given The vertical shear force V = 5 kN, the planks' thickness t = 10 mm the top flange width w = 130 mm, the bottom flange width w = 110 mm, the web height h = 240 mm, and the allowable force on each nail Fall = 1.5 kN, calculate the 2nd moment of area of the entire cross section I in 10. mm, the shear stresses at the neutral axis TNA in MPa and the maximum spacing between nails & in mm. Enter your answers in the boxes below. The answers are acceptable within a tolerance of 1 10%.mm for the 2nd moment of area 0.1 MPa for the stress and 1 mm for the spacing. I: 10.mm(3 mark) TNA: MPa (3 mark) mm (3 mark)
