with measurement of the pore water pressure as shown in Figure Q2(b). If
the deviator stress is applied on sample 1 = 48 kN/m², sample 2 = 105 kN/m²
and sample 3 = 198 kN/m²;
Compute Mohr-circle in term of total stress and effective stress on
the same graph.
(ii)
Compute the cohesion and friction angle for total stress and effective
stress.
(iii)
Based on the answer in Q2(b)(ii), briefly discuss on the result
obtained.
