- Please give proper answer List the two main kinds of line defects occurring in solid materials which describe macroscopic mechanical behavior of solidsHow does crystallinity affect the mechanical properties of materials. with proper referenceA single crystal of silver (FCC structure) is oriented such that a tensile load of 1,000,000 N is applied along the [001] direction. The single crystal is cylindrical and has a radius of 18 cm. The slip system for the FCC crystal structure is 111〈110〉. Using the FCC unit cell below, sketch a (111) plane and, using arrows, indicate two different 〈110〉 directions within this plan. Compute the resolved shear stress (in MPa) in the [101] direction on the (111) plane. If the critical resolved shear stress is 2.0 MPa, will the crystal yield? (explain how the answer is obtained
