Calculating stress, strain and Young's modulus?

[QUOTE="Chestermiller, post: 4344121, member: 345636"] The strain was correct, although they may have given the result with more digets 0.00153. The calculation of the cross sectional area is correct. The calculated stress is correct, but perhaps should be expressed as 11.6 MPa. The calculated Young's modulus, which is the stress divided by the strain is incorrect. You made a mistake in arithmetic. 11.6/0.00153 = 7584 MPa = 7.58 GPa. [/QUOTE]
