An axial load P is applied to a 220"-long bar with stepped cross-section as shown in Fig. 1. The area of each cross-section is shown in the figure. The stress-strain relation for the material used can be expressed as follows: 20,000€ 1+ 400€ 0 = 0 ≤ ≤ 0.03 (0 = ksi) in which the strain & is nondimensional and o has units of kips per square inch (ksi). You may assume that the elastic modulus is the same for the entire bar and is equal to the slope of the stress- strain curve at the origin. Determine the axial elongation (in inch) and strain (in %) of the bar if P = 30 kips A₁ = 5 in² A-15 in2

Two bars AC and BC of the same material support a vertical load P (see figure). The length L of the horizontal bar is fixed, but the angle fl can be varied by moving support A vertically and changing the length of bar AC to correspond with the new position of support A. The allowable stresses in the bars are the same in tension and compression. When the angle ft is reduced, bar AC becomes shorter, but the cross-sectional areas of both bars increase because the axial forces are larger. The opposite effects occur if the angle 0 is increased. Thus, the weight of the structure (which is proportional to the volume) depends upon the angle ft. Determine the angle ft so that the structure has minimum weight without exceeding the allowable stresses in the bars. Note: The weights of the bars are very small compared to the force P and may be disregarded.
