Textbook Question
Chapter 6, Problem 9ICA
Suppose that the earth were a smooth sphere and you could wrap a 25,000-mile-long band snugly around it. Now let us say that you lengthen the band by 10 feet, loosening it just a little. What would be the largest thing that could slither under the new band (assume that it is now raised above the earthʼs surface equally all the way around so that it doesnʼt touch anywhere): an amoeba, a snake, or an alligator?

A wheel of diameter 150.0 mm and width 37.00 mm carrying a load 2.200 kN rolls on a
flat rail. Take the wheel material as steel and the rail material as cast iron. Assume the
figure given, which is based on a Poisson's ratio of 0.3, is applicable to estimate
the depth at which the maximum shear stress occurs for these materials. At this critical
depth, calculate the Hertzian stresses σr, σy, σz, and Tmax for the wheel.
