Question

Q4: A solid bar is having uniform cross section 15 mm x 15 mm throughout the length and is made up of a material having shear modulus equal to 0.1165 x 104 kN/cm2. When the bar is subjected to a tensile force of magnitude 19000 N, the changes in the lateral dimensions of the bar was found to be 14.885 mm x 14.885 mm. Identify the elastic properties and determine the value for the Young’s modulus of the material. What changes will happen to the volume of the bar due to the applied tensile force and by considering the length of the bar equal to 3.75 m? Conclude the relationship between various elastic constants for the solid bar based on the results obtained.
