Stress Analysis (Direct Stresses)
In Programme 3 we saw how external loads on a pin jointed frame structure induced axial forces in the individual members of the frame. In Programme 4 we saw how external loads induced shearing forces and bending moments in beams. We now begin to look more closely at the way in which the material of which the structure is made reacts to the effect of loading. We start in this programme by considering in detail the behaviour of structural members subjected only to axial tensile or compressive forces. The effect of shearing forces and bending moments will be considered in subsequent programmes
