Question: 11 a solid circular rod that is 500 mm long...

Question details

1.1 A solid circular rod that is 500 mm long and with an 18 mm diameter is subjected to an axial force of P 42 kN which elongates the rod by 1.56 mm. Under loading, the diameter of the rod becomes d- 17.9824 mm. Determine the modulus of elasticity, E, and the modulus of rigidity, G, of the material. Assume the material does not yield. [Hint: youll need eqn. 3-11 from the text for G 20.1 GPa] The figure below is an Elastic - Perfectly Plastic mathematical approximation of the stress strain behavior exhibited by the material of the rod in question 1.2 Stress (ksi) 50 Strain (in/in) 003333 .20
