(A) he figure below shows three metal cubes A, B, C of side 100 mm in direct contact, resting on a rigid base and confined in x-coordinate direction between two rigid end plate. If the upper face of the center cube B is subjected to uniform compressive stress of 0.5 kN/mm², compute for cube B, the following: (i) The direct stress in x-direction (₂) ? (ii) The direct strains in the three coordinates directions x, y and z (iii) The volumetric strain Rigid A E = 150 kN/mm² μ= 0.25 o₂ = 0.5 kN/mm² B E = 200 kN/mm² μ = 0.3 Rigid C E = 150 kN/mm² μ = 0.25 Rigid
