Question

Please make all the math thanks ! specially in part b) explain mathematically and physically

a) An aluminum cylinder with a radius of 1.75 cm and 6.2 cm in length is subjected to a tensile force of 3,380 N. How much does it deform in its cross section? Young's modulus of aluminum is 7.0 × 108 ? / ?2, and the Poisson number is 0.34.

b) Is the following statement true ?: By elastically elongating a rod of any material, its cross section is reduced, in such a way that the volume is preserved. Under what conditions would it be met?

in such a way
