An aluminum wire of length 2.0 m and diameter 5 mm is used to hang a load of 100 kg. The modulus of elasticity of aluminum is 65 GPa and consider a Poisson’s ratio of 0.30. a) Calculate the final length of the wire when the load is applied. b) Calculate the final diameter of the wire when the load is applied.  (round off your answer in 5 decimal places).

SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer

Suppose that an axle component of an automobile is fabricated from steel alloy with a plane strain fracture toughness of 45 MPa.m0.5 is exposed to a stress of 255 MPa and if the maximum internal half-length of the crack of the material is 3.2 mm, compute the dimensionless parameter (Y) of the material.
