The bar is made of an aluminium alloy having a stress€“strain diagram that can be approximated by the straight line segments shown. Assuming that this diagram is the same for both tension and compression, determine the moment the bar will support if the maximum strain at the top and bottom fibres of the beam is ε_max= 0.05.
