Now that you've assembled an outline of your paper, do you feel it makes a unified argument? Can you see how the parts of the essay relate to each other? If not, what do you think you can do to address the problem? Do you have any questions for your classmates? If you do think your paper is unified, what advice would you give to fellow classmates to help them achieve success? 200 to 300 characters

Course: Soil mechanics
Theme: Fellenius Method
There is a soil with the following characteristics: cohesion of 0.4 kg / cm2, friction angle 33 ° and dry density of 1.7 gr / cm3 and when saturated, effective cohesion of 0.2 kg / cm2, effective friction angle of 24 °. and a saturated density of 2.2 gr / cm3. The slope under evaluation has a 38 ° inclination, the rocky layer is 11 meters away, finding the stability of the slope in a dry and saturated condition, in addition to evaluating the critical height.

Pure iridium metal is one of the densest elements at 22.6 g/cm3 . Compute the settling velocities of spherical iridium particles of the given diameters, d_p, in the given fluids.

(a) d_p = 2 μm in air (T = 293 K, P = 1 atm, ρ_a = 1.2 kg/m3 , μ_a = 0.0181 g m^-1 s^-1 )

(b) d_p = 100 μm in water (ρ_w = 1.0 g/cm3 , μ_w = 0.010 g cm^-1 s^-1)

A 30-kg uniform circular plate of radius r is supported by a ball-and-socket joint at point A and is at rest in the vertical xy plane when a bullet with a mass of 15g is fired with the velocity Vo = (-210m/s)k and hits the plate at point C. Knowing that r = 400 mm and h = 700 mm, determine (a) the angular velocity of the plate immediately after the bullet becomes embedded (b) the impulsive reaction at point A, assuming that the bullet becomes embedded in 1.1 ms
