Engineering - November 2006

A craft company wants to develop and market decorative Styrofoam snowmen. After some discussion with the company executives about the proper proportion of head and body, a decision was made to use two spheres. The larger body sphere will be 1.6 times the diameter of the smaller sphere (head). The base of the body sphere will be cut off at 0.8 of its radius. The base of the smaller sphere will be cut off at the neck at 0.9 of its radius to fit exactly with a matching cut at the top of the body sphere (the two radii of the cut surfaces of the two spheres will be exactly equal).
Derive an equation in terms of the radius of the head (r) that will allow you to calculate the volume of material required for manufacturing the snowmen. Simplify to a minimum number of terms.

I know that common practice is to place a base course material (rough aggregate) down before placing bituminous asphalt. What would be the outcome (or potential problem) with re-paving over a trench after placing a sand-cement slurry and no base course?

Two passenger trains each with four carriages face one another on a main line. Adjoining the main line is a siding. The siding is only long enough to take an engine and two carriages.

i have to measure lengths of paper when transferring from a 4 inch diameter roll to a 2 inch, typically in 4,5,8.and 10meter lengths.i use an approximate method based on the number of turns it takes to roll off 1 metre. and multiplying it by the number of metres i need. obviously,however,the diameter of the smaller roll increases the more paper is rolled on.making this method increasingly more inaccurate the more paper required.does anyone know of a wheel measuring device that would be in contact with the paper on the larger roll,giving a more accurate read out?
