Express the yield stress in terms of resilience.
Calculate the modulus of resilience for the material having the
stress-strain behavior shown in the Animated Figure 6.12.

What are the units for modulus of resilience if you are using psi for stress and in/in for strain?
5) Find the resilience and the toughness for a metal that experiences both elastic and plastic deformation. Assume a linear elastic relationship for the elastic deformation (Hooke's Law) and that the modulus of elasticity is 172 GPa and that the strain at yield is 0.01. For the plastic deformation, assume that the relationship between stress and strain is described by-ken and that k-6900 MPa and n-0.30. Plastic deformation occurs between the strain at yield, 0.01, and the failure strain, 0.75.
Question 1: The stress-strain diagram for a material is shown in figure. Find the following properties of the material. (a) Yield load if the diameter of specimen at yielding is 13mm. (b) Modulus of resilience (c) Elastic Strain Stress (MPa) CS Scanned with CamScanner 0.001 0.003 Strain

Question 5: Draw a typical stress-strain relationship (graph) for steel subjected to tension. On that graph, show the initial tangent modulus (slope only), proportional limit, elastic limit, the yield strength, ultimate strength and rupture stress. Also indicate the area that would be used to determine the modulus of resilience. (2+6+3 =11 Points)
no explanation required, thank you 33. Resilience refers to: A) the ability to cope with stress and adversity, to adapt to negative or unforeseen circumstances, and to rebound after negative experiences. B) positive thoughts that lead to relaxation and calmness. C) perceiving events as taxing and exceeding the ability to cope. D) the total amount of negative events experienced over a lifetime. 35. Researchers have investigated possible gender differences in the frequency of daily hassles. What does this research show?...
Maximum stress that a material can resists is called yield stress. True or False?
