$Complete assignment on paper and turn in at the beginning of class on the due date. For a materials stress-strain curve shown below, determine the following properties (and show your work where applicable): 1. The materials Elastic Modulus. 2. The materials 0.2 % offset yield stress. 3. The maximum allowable tensile force that can be applied to a 2 diameter rod made of this material without causing permanent deformation (use the 0.2% offset yield stress to define when permanent deformation occurs). 4. How much would a 15-ft long, 2.53-in diameter rod made of this material elongate while subjected to a tensile force of 150 kip? Hint: deformation is related to strain; strain is related to stress via the stress-strain curve. 5. Assuming that the material fractures at 35 ksi, what is the materials modulus of toughness?$

$Hint: deformation is related to strain; strain is related to stress via the stress-strain curve. 5. Assuming that the material fractures at 35 ksi, what is the materials modulus of toughness? Hint: count squares (and take into account the area of each square) to get an estimate for an area under the curve. o(ksi) 40 35 30 25 20 15 10 e (in./in.) 00.002 0.004 0.006 0.008 0.010ni Figure: 03 PROB_17-18$
