Vane shear tests were conducted in the clay layer. The vane dimensions were 63.5 mm (D) x 127 mm (H). For the test at A, the torque required to cause failure was 0.051 Nm. For the clay, given: liquid limit = 46 and plastic limit = 21. (a) Estimate the undrained cohesion of the clay for use in the design by using Bjerrum's correction. A = 1.7 – 0.54 log[PI(%)]

A vane shear test was conducted in a saturated clay. The height and diameter of the rectangular vane were 4 in. and 2 in., respectively. During the test, the maximum torque applied was 230 lb-in. The clay soil has a undrained shear strength of 7.844 psi. It has a liquid limi of 58 and a plasic limi o 29. What would be the corrected undrained shear strength of the clay for design purposes? Using Bjerum's relationship for λ. λ = 1.7 - 0.54 log[PI(%)]
The grain of a wooden member forms an angle of 15° with the vertical. Determine the in-plane shearing stress parallel to the grain using Mohr’s circle, assuming that τxy = 251 psi.Answer: 217 psi.
Someone can help me on this one. Thanks
Answer in True Or False
A Soil Element is shown in figure . Determine the Following: a. Maximum and Minimum Principal Stress b. Normal and Shear stresses on plane AB
If both the major and minor principal stresses for a soil element are known, as well as the strength parameters c'and o': A) Derive the formula that gives the orientation (the angle 0) of the theoretical failure plane. Hint: for the diagram below, assume 0₁ is acting in the vertical direction on the soil element (typical case) - i.e. the orientation of the failure plane with be measured on the Mohr's Circle from the Pole (which will be at 03). Remember a useful property of circles in terms of angles... Øs 03 01 B) Relate your answer from Part A to the failure plane assumed in Rankine's Active Earth Pressure. You can show this relationship with a simple sketch.
