5- The shear strength of a normally consolidated clay can be given by the equation te= o'tan 27°. Following are the results of a consolidated-undrained test on the clay. Chamber-confining pressure = 3,130 lb/ft² ● Deviator stress at failure = 2,510 lb/ft² a) Determine the consolidated-undrained friction angle b) Pore-water pressure developed in the specimen at failure
