Question
In a drained triaxial compression test, a sample of sand fails at deviator stress of under confining pressure of . The angle of internal friction (in degree, round off to the nearest integer) of the sample, is _______.
Correct answer
36 to 38
Solution
Step 1: Identify given parameters. Confining pressure , Deviator stress .
Step 2: Calculate major principal stress .
Step 3: For sand (cohesion ), the failure criterion is .
Step 4: Substitute values: .
Step 5: Solve for : .
Step 6: Rounding to the nearest integer, the angle of internal friction is .
Step 2: Calculate major principal stress .
Step 3: For sand (cohesion ), the failure criterion is .
Step 4: Substitute values: .
Step 5: Solve for : .
