2. A standard brick ( dimensions 200mm x 100mm x 65mm) is compressed lengthwise by a
force Pas shown. If the ultimate shear stress for the brick is 8MPA, that occurs at an inclination
of 45° with the horizontal, and the ultimate compressive stress is 26 MPa, what is the axial
deformation of the brick? Modulus of elasticity of the brick is 2.65 GPa.
