Question: problem 1 calculate the elongation of a 25 inches long...

Question details

Problem 1 Calculate the elongation of a 25 inches long cylindrical titanium rod with the diameter of 0.5 inches upon application of the tension force of 10,000 N. Assume that Youngs modulus of titanium is 100 GPa. Problem 2. As a Chief Medical Officer, you are in charge of choosing a material for fracture fixation rod (L-10 cm, cross-sectional area A-50 mm2), which shouldnt extend more than 0.5 mm under tensile load of 3,500 N. A new composite polymeric material with Youngs modulus of the E-7.0x108 Pa has been recently introduced to the market. A) Can you use this new material for this application? Provide calculations B) What types of bonds are responsible for mechanical properties of metal and polymeric materials, respectively?
