simple harmonic motion

lavender, 30 (Kuala Lumpur)

a bar with a diameter of 30 mm and 80 mm long is subjected to a tensile force of 100KN. the proof stress is 230 MN/m^2. as a result of this bar has been elongated by 0.0585mm nad change the diameter to 29.994mm determine:
- the tensile stress
-the tensile strains in x-xdirection
-the tensile strain in y-y direction
-modulus of elasticity
-strain energy
-safety factor
-poisson ration
