A jointed rock sample is subjected to 20 MPa vertical stress as shown in the figure.
The modulus of elasticity of the rock is 10 GPa and the normal stiffness of the joint surface is 5 GPa/m. Assuming one-dimensional elastic behaviour of rock and joint, the displacement in mm of the loading surface AB is __________. [rounded off to 1 decimal place]
