Q1:

Through a point in a loaded soil, the principal stress is maximum on

A minor principal plane

B intermediate principal plane

C major principal plane

D none of these.

ANS:C - major principal plane

Through a point in a loaded soil mass, the principal stress is maximum on the major principal plane. The major principal plane is the plane on which the maximum principal stress acts. The intermediate principal plane is where the intermediate principal stress acts, and the minor principal plane is where the minimum principal stress acts. Therefore, the correct answer is: major principal plane.
