2 - A frame structure carries a sign, as shown in the figure below. The sign is made of steel (with mass density of 8000 kg/m³) and of uniform thickness. What is the maximum thickness tmax of the sign such that the allowable shear force and bending moment within the frame structure are not exceeded: Vallow = 8 kN and Mallow pins at points A, B, and C. The sign weight is transferred through cables CE 12 kN-m. Assume the frame members are weightless. There are and DF. 1m + 4m А 2m |C E F 1m 3m 1m B.

Pin-connected rigid bars AB, BC, and CD are initially held in the positions shown by taut wires (1) and (2). The bar lengths are a = 36 ft and b = 27 ft. Joint Cis given a horizontal displacement of 5.7 in. to the right. (Note that this displacement causes both joints B and C to move to the right and slightly downward.) What is the change in the average normal strain in wire (1) after the displacement? B (1), a (2) Answer: = i (0)

The initial compressive force of a steel column can be determined by Euler's buckling formula. The column has the following properties: A = 9484 mm² Fy=345 MPa x = 164 x 106 mm4 ly = 23 x 106 mm4 Proportional limit, fs = 290 MPa The x-axis has an unbraced length of 10 m which is pinned at the top and fixed at the bottom with an k = 0.70. The y-axis has unbraced length of 5 m due to the bracing at the mid-height. Compute the initial compressive load of the column. Select the correct response: 6606.59 KN 3706.14 KN E = 200 GPa 1816.01 kN 926.53 kN

Figure below shows a uniformly tapering bar of rectangular cross-section of length L and thickness t. The width of the bar at one end is b₁ and the width at the other end is b2, where (b₂> b₁). The bar is subjected to an axial force P. The axial deformation due to load P is given by _mm. b₂ PL atE b₁ = 20 mm b₂-40 mm -In () then the value of (a + c) is
