question_answer 6)

The edge of aluminium cube are 10 cm long. One face of the cube is firmly fixed to a vertical wall. A If mass of 100 kg 4 & then attached to the opposite face of the cube. The shear modulus of aluminium is 25 G Pa. What is the vertical deflection of this face? [V=0cdot 32{{m}^{3}};]

Answer:

[B=1cdot 6times {{10}^{11}}Pa]                 [vartriangle V=frac{text{pV}}{text{B}}=frac{left( 1cdot 1times {{10}^{8}} right)times 0cdot 32}{1cdot 6times {{10}^{11}}}]                 Shearing strain [=2cdot 2times text{1}{{text{0}}^{text{-4}}}{{text{m}}^{text{3}}}]                 Or [because ]
