A single crystal in the form of a cube has two possible slip planes. (1) and (2). as shown in the sketch below. Each of these planes has two possible slip directions, (a) and (b), as is also shown. The angle between the tensile load axis and slip plane normal for both slip planes is 450 40 <plane (1)> <plane (2)> a) If a stress is applied to this crystal in the direction noted, specify which particular (eg. plane (1),...

EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...

Let's regard the mighty methane molecule (CH4) as a rigid tetrahedron, with the C atom at its center, and CH bond lengths of 1.1 Å (a) Find the position of the center of mass of the molecule. (c) What is the moment of inertia about an axis which is one of the CH bonds'? (d) Show that the moment of inertia about either of the two perpendicular axes is the same. Thus the moment of inertia is independent of the...

7. We know that well-defined preferences over two goods have the properties that () indifference curves are negatively sloped, and (ii) that indifference curves are convex (so that chords between two points on the indifference curve lie in the set ((c, y) such that (c,y)(coyo) when (co. o) is a point on the indifference curve). Suppose that good y is "clean air" and good c is consumption of all other goods. This problem gets you to determine what these two...
