In an unconfined compression test on a saturated clay, the maximum proving ring dial reading recorded was 240x10³ mm, when the axial shortening of the specimen having an initial height of 70 mm and an initial diameter of 36 mm, is 12 mm. If the calibration factor of the proving ring is 3.2 N/10³ mm, calculate the unconfined compressive strength and the undrained shear strength of the clay.

Question
(a) In an unconfined compression test on a saturated clay, the maximum proving ring dial
reading recorded was 240x103 mm, when the axial shortening of the specimen having
an initial height of 70 mm and an initial diameter of 36 mm, is 12 mm. If the calibration
factor of the proving ring is 3.2 N/10³ mm, calculate the unconfined compressive
strength and the undrained shear strength of the clay.
