Figure 2 shows a horizontal beam AB. It is pin-supported at end A and carrying a load Q at end B. The beam is supported at C by a pinned-end column. The column is a solid steel bar of square cross-section having length L and side dimension b = 60 mm. Based upon the critical load of the column, if the allowable load Q is given by 109 KN with the factor of safety n = 2.0 with respect to buckling, determine the length of the column. E = 200 GPa 2d Q Figure 2 (201

A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 12600 ksi] rods, and a solid steel [E = 32100 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.61 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.42 in. Assume L₁-53 in and L₂=73 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P = 21 kips is applied. Answers: 0₁ = i 02 = i L₂ (2) B ksi. ksi.
Design a wide flange W column 8 m in height to support an axial dead load of 1000 kN and a live load of 1200kN in the interior of a building. The column base is rigidly fixed to the footing and the top of the column isrigidly framed to very stiff girders. Assume that bracing is provided to prevent side sway in the weak axis/planeof the column (you don’t have to consider slenderness in this direction), but side sway is not prevented aroundits strong axis. Select an economical W shape.
Consider the steel truss and member cross-section presented in figures below. All the members of the truss have the same cross-section as shown in the figure to the right. They all also have a Young's Modulus of 210 GPa. What can the highest value of force F be before member AC fails by buckling? Force 1AN - 300 mm 40° 4 m $35 mm 7m 300 mm 8 m 35 mm 35 mm 35 mm Please provide your answer in kN.
A torsional moment T = 8,019 Nm and a load P = 39,980 N are applied at the same time to a circular hollow shaft of unknown length L, as shown in Figure Q8. The load P is applied in the centre of the shaft's circular cross-sectional area. The shaft has an inner diameter d = 38 mm and an outer diameter D = 90 mm. Point A in Figure Q8 is on the outer surface of the shaft. Figure 8 Calculate the maximum principal stress at point A. Use π = 3.14159 if needed. Calculate your answer in the unit: mega-Pascal (MPa). Report you answer to 3 decimal places.
A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 15800 ksi] rods, and a solid steel [E = 27600 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.62 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.41 in. Assume L₁=30 in and L₂-62 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P=32 kips is applied.
