If the temperature of the bar is raised from 25°C to 75°C, find the stresses induced in each rod by assuming (a) if the supports do not yield and (b) if the supports yield by 0.25 mm. Take E1= 200 kN/mm2, E2 = 30 kN/mm2, E3 = 100 kN/mm2, And, a1= 1.2 x 10-5/°C, a2= 1.8 x 10-5/°C d3= 1.6 x 10-5/°C Q3/ * 0= 150 mm 0= 100 mm 0= 50 mm Figure 2 200 mm 300 mm 500 mm (1) 01= 194.78 N/mm2, a2= 48.7 N/mm2, 03= 21.64 N/mm2/(2) 01= 133.14 N/mm2, 02 33.28 N/mm2, a3= 14.79 N/mm2 (1) 01- 184 3anm2, 92- 44.73 N/mm2. 03- 24.64 N/min2/ (2) a1 143.14 N/mm2 o2 36 21 N/mm2, 03-14.79 N/mm2 (1) a1- 190.28 N/mm2, 02 48.26 N/mm2,

3. Assume the plane stress state: ơ1 = 0, 02 = 20, T12 = 15 (all stresses in ksi). If oz alone is increased until the maximum shear stress t1, in the material reaches ±20 ksi, what is the value of o, at this point? HINT: this is relatively easy to figure out if you construct a Mohr's circle for the initial stress state and then consider what happens if o, is replaced with Ao2 and you solve for A when the maximum shear stress (from the circle geometry) reaches ±20 ksi.
Use the engineering stress strain diagram provided below to answer parts (A) to (H) below (the stress-strain diagram bas already been drawn for you): stress strain diagram 400 350 0 300 0 250 0 200 0 150.0 100.0 50.0 O 05 0 1 0.15 strain A. Determine the tensile strength of this alloy. B. show the elastic, plastic and total strain on the diagram stress (Mpa)
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).
