2.1: 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 None 2. Deformation is the movement of a point relative to another point on a deformable body. True False None 3. In Lagrangian strain, the original geometry is used as reference geometry. True False None 4. In Eulerian strain, the original geometry is used as reference geometry. True False None 5. Positive shear strain results in increase of angle from a right angle. True False None 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 None 7. Strain has nine components in three dimensions. True False None 8. Strain has six independent components in three dimensions. True False None 9. At a point in plane strain there are three independent strain components. True False None 10. At a point in plane strain there are always four zero strain components. True False None Do you have any comments or suggestions? Please send them to author@madhuvable.org Time's up
