Question: a pinjointed framework is supported and loaded as shown in...

Question details

A pin-jointed framework is supported and loaded as shown in Figure 6. TIh framework is attached to a wall by a frictionless hinge at A and is supporte horizontally, but is allowed to move vertically at E, as shown. A load is applied a C whose horizontal and vertical components are Wand 2W respectively. (a). Determine the axial force in each of the seven bars, indicating whether they are (70% (b). Assuming Eulers formula is valid in this case, calculate the maximum valueo may assume that Youngs modulus for this material is 190 GPa and the bars ar in tension or compression. the parameter W which will cause the most highly loaded bar to buckle. You all manufactured from the same tubular section whose outer diameter is 20 mm and whose wall thickness is 4 mm. (30% Page 5 of 6 1 m 2W 1 m 1 m
