Answer 1

To calculate axial deformations using Hooke's Law it is important that the stress in the axial member exceed the proportional limit. O True Question 18 The principle of superposition is valid provided that (choose all that apply) Yes Modulus is small The loading is linearly related to the stress or displacement. Poisson's ratio y s 0.4 loading does not significantly change the original geometry of the member. Question 19 For axial deformations over segments where PA and E are constant, summations instead of integrals can be used. True O False Question 20 The image below, showing how localized deformations disappear as you move further from the applied load is an illustration of what principle? Load distorts lines located near load O Superposition Vlasticity O St. Venant's O Hooke's Law
