1. A copper wire 3m long is stretched to increase it’s length by 0.3cm. Find the lateral strain produced in the wire. If poisson’s ratio for copper is 0.26
2. A circular bar has original length of 3.0 m long and 50 mm diameter. The bar is compressed by a force of 35 kN and it shortens by 0.4 mm. Determine the elastic modulus for the material of the bar.
3. A circular steel bar with 50 mm diameter and 250 mm length is stressed to 280 MPa. If the elastic modulus of the steel bar is 205 Gpa, calculate the strain and force applied to the bar.
4. A metal tube with 2.25 m long carries a tensile load and the maximum stress in the tube should not exceed 70 MPa. Determine the extension of the tube when subjected to the tensile stress if the elastic modulus of the material is given 100 GPa?
5. A steel bar has 2 m long and 0.5 m diameter. It carries a load of 20 MN. Given that the modulus of eleasticiy of the bar is 200 GPa, calculate the compessive stress and strain. Determine how much the bar is compressed?
