A consolidated-drained triaxial test was conducted on a normally consolidated clay. The results are as follows: - Confining pressure, σ! = 250 kPa - Deviatoric stress at failure, (σ")# = 275 kPa Determine: (a) angle of friction ϕ′; (b) angle θ that the failure plane makes with the major principal plane; and (c) normal and shear stresses on the failure plane

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
