Question

Question 13 Define a homogeneous material Material has uniform properties throughout Material exhibits little or no yielding before failure. O Material exhibits little or no yielding before failure. O Material has temperature dependent refractive index. Question 14 Which of the following are true of ductile materials? Fails suddenly without warning, Can be subjected to large strains before failure May exhibit necking prior to failure Shows signs of failure prior to rupture Question 15 The ratio of shear stress to shear strain is the slope of the shear stress-strain diagram belowyielding. This ratio is called: O E-Young's Modulus O G-Shear Modulus O V-Poisson's ratio Question 16 To set up an equation using the force method, we first Remove one of the redundant supports. o Ignore internal forces O Set both external reactions equal O Add a redundant support

Answer 1

13 homogeneous means uniform uniform properties through out

14. Except fail suddenly without warning all are true this is the property of ductile material to allow large strain before fracture and rupture

15 ans shear modulus ratio of shear stress and shear strain

16 ignore internal stress only external forces considered in the set up
