A cast-in-place (CIP) cantilever wall is required to maintain the grade for a freeway. A preliminary wall dimension is shown in Figure P15.22. Determine the stability of the wall and show how you would provide adequate drainage. Use Rankine's method to calculate the lateral forces. Neglect the passive resistance at the front of the wall.
An equal-tangent crest vertical curve is designed with a PVI at station 110+00 and a PVC at station 107+43.3. if the high point is station 110+75.5 what is the design speed of he curve?
What measures of performance are derived from each?
Sketch and identify the Tresca (maximum shear stress) and von Mises (maximum distortion energy) failure criteria in two-dimensional principal stress space (i.e., ?2 vs. ?1) for the above material.
Determine the force in each member of the loaded truss.
Calculate the size of an anaerobic digester required to treat the sludge from a primary clarifier designed to treat 38,000 m3/d of sewage. The quantity of dry volatile solids removed by the plant is 0.15 kg dry solids/m3 sewage.
a poorly designed 100 ft long homogeneous barge runs on diesel fuel, the fuel is held in a 2' tall trapezoidal tank of the same length as the barge. and is located at the bottom of the barge hull.
