2 BUCKLING QUESTION a) Briefly explain what is the difference between the failures due to instability, yielding, and plastic collapse in the context of bending failures of structures. b) The following figure (Figure 3) shows a hinged structure (not to scale; dimensions in mm; and B, C, D, E are all pin joints) carrying a bucket at the end of its horizontal arm. The spring of stiffness k has a length such that any deviation from the vertical of the upright arm to which it is attached exerts a restoring force on the arm. What spring stiffness k should be chosen in order that the structure collapses when water of total mass 5kg is poured into the bucket? (Hint: consider the instability when the vertical components are displaced by a small angle with respect to the vertical). Note: Dimension "a" in the following Figure is equal to 500 A 5g B.

For a concrete column that is part of a braced frame, if the column is square, tied, 18 inches per side, 16 feet long, classify the column as slender or non slender. Assume that at one end of the column a clockwise moment of 100 k-ft is present, and that at the other end of the column a counter-clockwise moment of 25 k-ft is present. You may assume that K=1.
The pin-connected structure shown in the figure consists of a rigid beam ABCD and two supporting bars. Bar (1) is a bronze alloy [E = 101 GPa] with a cross-sectional area of A₁ = 230 mm². Bar (2) is an aluminum alloy [E = 71 GPa] with a cross-sectional area of A₂ = 740 mm². All bars are unstressed before the load P is applied; however, there is a 4-mm clearance in the pin connection at A. Assume L₁ = 2040 mm, a = 1020 mm, b = 630 mm, c = 460 mm, and L₂ = 1470 mm.
