The in situ moist unit weight of a soil is 16.6 kN/m^3, and the moisture content is 19%. The specific gravity of soil solids is 2.69. This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted to a minimum dry unit weight of 19.5 kN/m^3 at the same moisture content of 19%, how many cubic meters of soil from the excavation site are needed to produce 2500 m^3 of compacted fill

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
