Coordination Number (CN) and Radius Ratio
In an ionic structure each cation tends to surround itself with anions; the number
that can be grouped around it will depend on the relative size of the cations and anions.
If you use the analogy of a soccer ball,
1. The density of Magnesium metal is 1.738 g/cm^3. It crystallizes in a face-centered cubic
structure. What is the volume of the unit cell in liters.
2. One form of silicon has density of 2.33 g/cm and crystallizes in a cubic lattice with a u

An estimate of the expected load on over-the-shoulder seat belts is made before designing prototype belts that will be evaluated in automobile crash tests. Assuming that an automobile traveling at 72 km/h is brought to a stop in 110
A bullet is fired with a horizontal velocity of 500 mls through a 3-kg
block A and becomes embedded in a 2.5-kg block B. Knowing that blocks A and B start moving with velocities of 3 mls and 5 mis, respectively determine
Four pins slide in four separate slots cut in a circular plate as shown. When the plate is at rest, each pin has a velocity directed as shown and of the same constant magnitude u. If each pin maintains the same velocity relative to the plat
