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.
A vertical 12-cm diameter piston-cylinder device contains an ideal gas at the ambient conditions of 1 bar and 24oC. initially the inner face of the piston is 20 cm from the base of the cylinder
Knowing that at t= 3s slider block C has moved 57 mm to the right, Determine the velocity of slider block C at t=0, (b) the acceleration of A and C, (c) the change in position of block A after 5s.
A paddle wheel, inserted inserted into the volume, does 720 KJ of work on the air. If the volume is 2 cubic meters, calculate the entropy increase assuming constant specific heats.
For determining the centroid of the area, two square segments are considered; square ABCD and square DEFG. What are the coordinates (x, y ) of the centroid of square DEFG?
Using an 9.34 in long wrench, the bolt has now been unscrewed a length of 1.10 in. The force of F={-52.7i +7.00j +6.00k} lb is still applied to the wrench at point B.
The influent flow is 380 Lpcd and the influent BOD5 is 200 mg/L. Pertinent data are: Primary clarifier removes 33% of the influent BOD5, and the state regulatory agency allows a volumetric loading of 0.48 kg BOD5 /(m3.day). Determine the reactor b..
Design a Portland cement concrete mix for a loading dock driveway slab. The concrete will be exposed to deicing chemicals and subjected to freezing and thawing in a moist condition. This is severe environmental exposure.
A line passes through the points (22 m, 19 m) and (-2 m,-5 m). determine the perpendicular distance d from the line to the origin O of the system of coordinates.
Write a paragraph explaining how the relaxation modulus of a plastic material measured in engineering practice. use a sketch.
A rectangular channel leading from an upstream lake has a bottom width of 20 ft, bottom slope of 0.0002, a Manning roughness factor of 0.016, a discharge of 403 cfs, and normal depth of 6.24 ft. Then at the downstream end the flow depth is 4.915 ft. ..
