A cohesive soil sample tested in an unconfined compression test failed by developing a failure plain when the axial load on the sample was 193 N. Determine the undrained shear strength, Cu (kPa) of the soil given the original diameter of the sample was 45 mm and the strain at failure was 9%. Provide your answer in kPa as a whole number.
