SOIL STRENGTH PROPERTIES AND THEIR MEASUREMENT
shear strength is taken as one-half the compressive strength. In the cone test, a cone with an angle 0 is forced into the soil [Figure 12-4(b)] under a force (Q), which may be its own weight. The shear strength is obtained from the relation KQ . Soil Strength Properties and Their Measurement
12.3 Stress, Strain, and Elastic Modulus
In other situations, the acting forces may be neither tensile nor compressive, and still produce a noticeable deformation. For example, suppose you hold a book tightly between the palms of your hands, then with one hand you press-and-pull on the front cover away from you, while with the other hand you press-and-pull on the back cover toward you.
