Problem 23SE

The article “Effect of Microstructure and Weathering on the Strength Anisotropy of Porous Rhyolite” (Y. Matsukura, K. Hashizume, and C. Oguchi, Engineering Geology, 2002:39–47) investigates the relationship between the angle between cleavage and flow structure and the strength of porous rhyolite. Strengths (in MPa) were measured for a number of specimens cut at various angles. The mean and standard deviation of the strengths for each angle are presented in the following table.

Can you conclude that strength varies with the angle?
