8-13. A structural member in a nuclear reactor is made ofa zirconium alloy. If an axial load of 20 kN is to be supportedby the member, determine its required cross-sectional area.Use a factor of safety of 3 relative to yielding. What is theload on the member if it is 1 m long and its elongation is 0.5mm? E - 100 GPa, ay - 400 MPa. The material haselastic behavior.

Given, E = 100 GPa σY = 400 MPa P = 20 kN The factor of safety = 3 Length (L) = 1 m Factor of…

Find the critical buckling load of the 7 m long, cross-section column made of A-36 steel with hinged joints at both ends (Figure 3). E=200 GPa
A long, slender structural aluminum [E = 69 GPa] flanged shape is used as a l = 9.2-m-long column. The column is supported in the x direction at base A and pinned at ends A and C against translation in the y and z directions. Lateral support is provided to the column so that deflection in the x-z plane is restrained at mid-height B; however, the column is free to deflect in the x-y plane at B. Assume that b; = 102 mm, d = 122 mm, t; = 8 mm, and tw = 6 mm. Determine the maximum compressive load P the column can support if a factor of safety of 2.9 is required. In your analysis, consider the possibility that buckling could occur about either the strong axis (i.e., the z axis) or the weak axis (i.e., the y axis) of the aluminum column. bf C L Lateral B bracing L 2 A
