1.2 – CONCEPT OF STRAIN For each of the questions below, choose the correct answer. Name Email 1. Displacement is the movement of a point relative to a fixed point on a deformable body. True False 2. Deformation is the movement of a point relative to another point on a deformable body. True False 3. In Lagrangian strain, the original geometry is used as reference geometry. True False 4. In Eulerian strain, the original geometry is used as reference geometry. True False 5. Positive shear strain results in increase of angle from a right angle. True False 6. The normal strain will be positive if the left end of a rod moves more than the right end in the negative x direction. True False 7. Strain has nine components in three dimensions. True False 8. Strain has six independent components in three dimensions. True False 9. At a point in plane strain there are three independent strain components. True False 10. At a point in plane strain there are always four zero strain components. True False Do you have any comments or suggestions? Please send them to author@madhuvable.org Time's up
