Hilda, Layla, and Saber were experimenting with a carbon steel rod in the chemistry laboratory. Hilda learned that the carbon steel has a strain hardening ratio of 0.841, yet it breaks at a force of 45 N. Layla and Saber calculated the 15 mm2 rod's yield limit. The information they got was lacking because they have failed to borrow an SEM, but they were able to calculate the spacing of the atoms. Determine the spacing of the atoms if the shear modulus is 0.3 GPa and the interatomic space is equal to 1.8 Å.​
