Every engineer is involved daily with some problem which requires the calculation of a numeric answer. These
calculations may be very complex or quite long and therefore require the use of a computing device other than
a pencil and paper. Many engineers are likely to turn to a computer to solve any calculations more difficult
than adding two numbers. However, many day-to-day types of problem solving are difficult and tedious to do by
hand, but really don't require the full capability of a computer,

In the field of mass properties engineering, these types of calculations may include such things as mass moments
of inertia, center of gravity or centroids. For work in the aerospace, shipbuilding or general transportation
industry, engineers may have to continually solve these formulas or others like them.
