Problem 1: When an axial load is applied to the ends of the bar shown at right, the total elongation of the bar between joints A and C is 0.10 in. In segment (2), the normal strain is measured as 900 microstrain (or equivalently, 900 ?in./in.). Determine both the elongation of segment (2) and the normal strain in segment (1) of the bar. Answer: ?L2 = 0.081 in; ?1 = 475 ?strain Problem 2: In the figure at right, the rigid bar ABC is supported by a pin connection at B and two axial members. A slot in member (1) allows the pin at A to slide 0.25 in. before it contacts the axial member. If the load P produces a normal strain in member (1) of -1500 ?in./in. (so that member (1) is in compression), determine the normal strain in member (2). Answer: ?2 = 0.003104

A pin-jointed structure is supported and loaded as shown in Figure 1. The structure is constructed from tubular steel bars of hollow circular cross-section whose external diameter is 50 mm and whose wall thickness is 5 mm. The Young’s modulus for the material is 200 GPa. (a). Determine the magnitudes and directions of the reactions at A and F. (b). Perform a simple test to determine whether or not the structure is statically determinate. (c). Calculate the axial force in bars EF, DF, CE, ED, CD and BD, indicating whether the bars are in tension or compression. (d). Derive an expression for the stiffness of an elastic bar subjected to axial loading conditions. (e). Calculate the stiffness and change in length of bar EF. (f). Calculate the effective slenderness ratio of bar DF and hence determine if the Euler buckling formula is valid for this bar. (g). Use the Euler buckling formula to determine whether or not buckling will occur in bar DF.

A system has been designed that is modeled as shown to the right. It consists of two solid 2014-T6 aluminum rods AB and CD with the given dimensions and 2 rigid plates, AC and BD. If the assembly is subjected to the external loading shown, determine the deformation of both rods AB (̈́ᴡ) and CD (̈́ᴄᴰ). Also determine the new diameter of rod CD, d'ᴄᴰ, after loading. Use the following parameters: dᴡᴠ = 0.5 in, dᴄᴰ = 0.3 in, L₁ = 20 in, L₂ = 10 in, L₃ = 40 in, P = 500 lb, and w = 20 lb/in.

An axial pull of 40 kN is acting on a stepped bar consisting of three sections of length 30 cm, 25 cm, and 20 cm, and of diameter 2 cm, 4 cm, and 5 cm respectively. If E = 2.1 × 10^5 N/mm^2, determine a) stresses in each section and b) total elongation of the bar. A brass bar having cross-sectional area of 1000 mm^2 is subjected to axial forces as shown below. Find the total elongation of the bar. Modulus of elasticity of brass = 100 GPa.
