Formula Sheet Normal strains = (0 +0k) Dilatation 1-2v -170 (9+0+0) e= The steel block shown in figure B2 is subjected to a uniform pressure on all its faces. Knowing that the change in length of edge AB is -1.2 x 10-3 mm, determine: (a) the change in length of the other two edges [15 marks] (b) the pressure p applied to the faces of the block. Take the Modulus of elasticity as E = 29 x 106 Pa and the Poisson's ratio as v = 0.29. C A 4 mm B 2 mm D x 3 mm [10 marks] Figure B1.
