Q1/A structural part is 1-meter-long and subjected to a 50 KN load in which this part must be deformed elastically without experiencing any permanent deformation. If you know that part is made of steel, brass, aluminum, and Titanium alloys and the yield strengths and densities of these alloys are: 860 MPa, 7.9 g/cm³; 415 MPa, 8.5g/cm³; 310 MPa, 2.7 g/cm³; and 550 MPa, 4.5 g/cm³ respectively. Based on these criteria, rank the alloys from the heaviest to the lightest in weight.

Learning Goal: A material is homogenous and isotropic when it has a modulus of elasticity that does not vary with direction and it has uniform properties throughout. When a point in a material is subjected to only normal stresses in three dimensions, but they are not necessarily equal, the state is called triaxial stress. When the response of the material is linear elastic, the strains along the three axes can be calculated using a generalized form of Hooke's law. Each strain depends on all three stresses because of the Poisson effect. €1 Figure 1 [0₂ - V (O₂ +0₂)] a 1 of 1 A cube is subjected to stresses with magnitudes a = 16 MPa, b = 26 MPa, and c = 5 MPa (Figure 1). What is the strain in the y-direction? Let E = 200 GPa and v= 0.26.
