Sometimes cos o cosa in Equation 7.2 is termed the Schmid factor. Determine the magnitude of the Schmid factor for an FCC single crystal oriented with its [120] direction parallel to the loading axis.The slip occurs on the (111) plane and in the [011] direction. i

Will the (211) plane produce an X-ray diffraction peak in the FCC structure? Why or why not?

Calculate the reflection loss when a beam of radient energy passes an empty quartz cell assuming the refrative index of quartz is 1.55

2) Consider two cubes of plastic and wood that are floating in water, each of side s. (see diagram). The density of the plastic is 80.0 % of the density water and the density of the wood is 60.0 % of the density of water. An aluminum block having base area s? is going to be glued on top of the plastic and wood system. The density of aluminum is 2.7 times the density of water. Assume the system stays upright (does not tip over). Alum block a) How tall does the aluminum block need to be if the top of the aluminum block will be at the surface of the water when equilibrium is reached ? Give answer in terms of s. woed water plastic on tup
