1.Determine the ultimate bearing capacity for a 0.85m by 0.85m square footing eccentrically loaded 0.04m on one axis and 0.08m on another axis
2.A cohesionless soil sample was subjected to a triaxial test. The sample failed when the minor principal stress (confining pressure) was 1200 lb/ft^2 and the deviator stress was 3000 lb/ft^2. Find the angle of internal friction for this soil.
3.A triaxial test was performed on a dry, cohesionless soil under confining pressure of 144 kN/m^2. If the sample failed when the deviator stress reached 395.8 kN/m^2, determine the soil's angle of internal friction.
4.A 10-ft beam AE is being lowered by means of two overhead cranes. At the instant shown, it is known that the velocity of point D is 24 in./s downward and the velocity of point E is 36 in./s downward. Determine (a) the instantaneous center of rotation of the beam. (b) the velocity of point A.
