Axial deformation and Poisson's ratio
Problem statement
A prismatic bar with a circular cross section is subjected to an axial tensile force of 85 kN. The bar is 3.0 m long and 30 mm in diameter. The bar is made of aluminum with E = 70 GPa and ν = 1/3. Calculate the elongation δ and the decrease in diameter.
Concepts: elongation, aluminum bar, tension, decrease in diameter, modulus of elasticity
