Answer is Not 43,-1 and 22.

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 ductile bar as shown in figure 1 has a yiel strength of oy = 390 MPa. Force F makes a 30° angle with the positive x axis. Deter- mined the magnitude of F that will cause yielding. Hint: Select the most loaded point in the structure and the failure theory to use according to the material (The standard one for this type of material). Refer to the lecture. 2 y 7 75 mm 500 mm F 300 mm X
