$2.$ The stress$-$strain diagram of an aluminium alloy is shown below. A specimen having a gauge length of $250mm$ and a diameter $25mm$ is stressed to $600$MPa. If the Poisson's ratio, $v$ for the material is $0\mathrm{.}33,$ determine the following:

i$.$ Modulus of elasticity

ii$.$ New length of the loaded specimen

iii. New diameter of the loaded specimen

iv$.$ Final length of the specimen when the load is removed using the permanent strain
