### 8. STRENGTH OF SOILS AND ROCKS

shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress (N/A) applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement. Bolt GradesIn that case, shear strength is important to you. Marks Standard Handbook for Mechanical Engineers lists Grade 5 fasteners as 120 ksi fasteners. This means the tensile strength is 120,000 lbs per square inch. It also lists Grade 8s as 150 ksi fasteners meaning the tensile strength

Shear strength is defined by the Mohr-Coulomb strength equation in terms of effective stress. In some cases the Mohr-Coulomb failure envelope [the line defined by the equation] passes through the origin. 19

### Plastic Material Properties Table Sort & Compare

Use our interactive properties table below to explore by property group, sort, or compare two or more plastic materials. Also, you may want to use our Plastic Material Selection Guide or Interactive Thermoplastics Triangle to assist with the material selection process based on your application requirements. For chemically resistant plastic, view our Chemical Resistance of Plastics chart. Strength and Grades of Fasteners QuadratecJan 07, 2017 · Shear strength of alloy steel is approximately 60% of its ultimate tensile strength. Reference to Table 1 shows that the yield strength of a Grade 8 bolt is higher than the ultimate strength of a Grade 5 bolt. The Grade 5 bolt will therefore always fail first whether in tension or shear. The only gotcha with the Grade 8 bolt is that Structural Bolts Feb-26-09 DONE - FastenalFor Bolt Ns calculation the root area must be used (as the shear plane intersects the threads), which is 0.302 sq-in. Now take this and multiply by the same 72,000 PSI and it results in approximately 21,740 pounds. By merely ensuring that the shear load is applied to the body of the bolt, the shear strength can improve by 8,260 pounds.
