If a soil sample tested in a direct shear box of 60 mm by 60 mm and the maximum readings for normal loads of 0.3, 0.5 and 1.0kN were 202, 265 and 511 kN, determine the strength parameters corresponding to effective stress. Please find: 1) UU test; Unconsolidated Untrained (Q-test or quick test) 2) CD test; Consolidated Drained ( S-test or slow test) 3) CU test; Consolidated Untrained (R-test) 4) UC test; Unconfined Compression (σ_3=0)
