1. If the fault has a friction angle of 30 degrees and cohesion of 2.0 Mpa, calculate the normal and driving shear stress on the fault plane at point 1. 2. The rock mass has HoekBrown values of m: 15 and S: 0.1, while Qc=24OMpa plot the Mohr circle and determine the Horizontal and vertical stress components with the associated Shear tensor at point 1. present the Mohr circle as well as the freebody diagram of the tensor
