compare the structural behaviour of timber
3. Compare the behaviour of timber, steel and reinforced concrete structural members under compression. If steel has a maximum allowable compressive strength of 300 N/mm2, Concrete 25 N/mm2, Reinforced concrete 30 N/mm2 and Timber class D70 parallel to the grain 23.0N/mm2 what is the maximum load a test piece of each material of dimensions 50mm x 75mm made from each of these materials can carry and what would be an acceptable factor of safety. Assume the length of each test piece to be no more than 75mm and ignore the concepts of effective length and radius of gyration use the formula below,
(Maximum load = allowable stress x Area)
