Two vanes A and B, with length-to-diameter ratios of 3 and 1 respectively, are each used to make a test at the depth in a clay layer. Both vanes have a diameter of 50 mm and the torque values measured were 95 N-m for A and 45 N-m for B. Find the values of undrained shear strength on the horizontal and vertical planes at this depth. Explain why undrained strength in clays may vary with direction.
