2 T « A solid round bar 60 mm in diameter and 2.5 m long is used as a strut. One. of the strut is fixed, while its other end is hinged. Find the safe compressive load for this strut, 4 gEuIef'S formula. Assume E = 200 GN/m? and factor of safety = 3. S

Answer ASAP A round vertical bar is clamped at the lower end and is free at the other. The effective length is 2 m. A horizontal force of 30 N at the top produces a horizontal deflection of 15 mm. What is the buckling load for the bar in the given conditions?

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

The maximum allowable tensile force in the members of the truss is (F)max = 5.7 kN, and the maximum allowable compressive force is (Fe)max = 3 kN. Take d-2 m. (Figure 1) Figure Part A Determine the maximum magnitude of load P that can be applied to the truss. Express your answer to three significant figures and include the appropriate units.

Two columns are of equal length, equal supporting conditions, made of the same material, but of different cross section as shown in the image below. The cross sections are equal in area but different in shape: one is square and the other is rectangular. Columns are loaded with a comprehensive force. Which of the following statements is true about whether one column or the other can be subjected to a greater force with buckling?   A. Both columns have equal critical force as their cross sections are equal in area. B. The column of the rectangular cross section is stronger against buckling. C. The column of the square cross section is stronger against buckling. D. Buckling is not possible for such structures. E. None of the above.
