Question

A metal wire having a diameter of 1.1390 mm and a length of 514.1 mm is deformed elastically in tension with a force of 1,660 N. Given that the elastic modulus and Poisson's ratio of the metal are 115 GPa and 0.3410, respectively, determine the change in diameter of the specimen (in mm). O-0.0257 mm -0.0492 mm -0.0055 mm -0.0107 mm Question 26 (1 point) Consider a natural gas pipeline. The pipeline is made of steel of thickness 2.00 cm. The steel is coated on the inside with a 0.100 mm layer of Ni. The concentration of natural gas inside the pipeline is 0.100 kg/m². The concentration outside is o kg/m3. The diffusion coefficient of natural gas in Ni is 2.01 x 10-21 m²/s and the diffusion coefficient of natural gas in steel is 7.00 x 10-17 m2/s. Calculate the flux of natural gas through the pipe assuming steady-state and linear geometry. O 5.27 x 10-16 kg/(m2.s) O2.00 x 10-18 kg/(m2.s) O 1.89 * 10-15 kg/(m2.s) O9.91 x 10-15 kg/(m2.s)
