Answer 1

Normal stresses act vertical and shear stresses act horizontal

Question 2

Define strain

Answer 2

The amount of deformation the material receives

Question 3

What is the difference between axial and lateral strain

Answer 3

Axial strain: deformation along the direction of loading

Lateral strain: deformation perpendicular to the direction of loading

Answer 4

Elastic
Elastico-viscous
Plastic
Rupture
