2) A small floor 4.8m x 4.2 m is to be supported by one main beam and 150 mm x 48 mm joist spanning between the wall and the beam, as shown in the figure below. a) Calculate the safe inclusive floor load if the stress in the timber has a maximum value of 7 N/mm². (4 marks) b) Choose a suitable section modulus for the main steel beam if the stress is not to exceed 165 N/mm². Ignore the weights of the joists and the beam.
