Determine the factor of safety against overturning about point A if = 3 .The factor of safety is defined as the ratio of the stabilizing moment divided by the overturning moment. The densities of concrete and water are = 2.40 and = 1 , respectively. Assume that the dam does not slide.
A body consists of a right circular cone whose base is 12 in. and whose altitude is 16 in. A hole 8 in. in diameter and 4 in. deep has been drilled from the base. The axis of the hole coincides with the axis of the cone. Locate the centroid of the..

Determine the maximum service load W (kips) at the mid-height of the beam-column shown in the accompanying figure 2.1. Assume the member is hinged with respect to bending in both x and y directions at the top and bottom.
Calculate the depreciation using straight-line, double-declining-balance (DBB), and MACRS (current IRS regulation) methods; and tabulate the depreciation schedule.
You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
A 10-mm diameter bar of 1040 carbon steel is subjected to a tensile load of 50,000 N, taking it beyond its yield point. Calculate the elastic recovery (or strain) that would occur upon removal of the tensile load.
develop the relation between bulk unit weight, specific gravity, void ratio and weight of water.
using darcy's law compute the quantity of flow, seepage velocity and contaminant loading of the river. ground water is flowing through unconfined uniform 3m thick sand aquifer and discharging to river.
Set up a table showing curve elevations at the PVC, at the PVT, and at the half-station points along the curve. Compute the station and elevation of the curve turning point.
time(in months) after a computer of brand is sold and needed repair is normally distributed with mean 36 months and standard deviation 4 month. if 1% of the super computer need services less than k months after they are sold, find the value of k.
Briefly describe electron and hole motions in a p-n junction for forward and reverse biases; then explain how these lead to rectification.
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
