The beam shown is subjected to symmetric loading as shown. Assume that the deflections are also symmetric, so that points A and D each deflect inwardly (parallel to the load P) by v0 Use conservation of energy to determine the deflection Note that both forces do work through the deflection The beam has uniform bending stiffness EI.
There are three reactors degrading a chemical biologically, at three degradation rates; i.e., 0.2 d^-1, 0.4 d^-1, and 1.0 d^-1. The residence time of the chemical in these reactors are 10 d, 5 d, and 55 d, respectively.
A groundwater is contaminated with methyl tertiary butyl ether (MTBE) at a concentration of 20 mg/L.the groundwater will be treated with an advanced oxidation process that involves formation of hdyroxyl free radical (OH*).
If this rod is to be used again with an initially straight axis, determine the maximum permissible deflection that may be allowed during testing procedures. Young's Modulus = 210 kN/mm2 and Yield stress of the steel= 240 N/mm2.
How much extra water does a 175 - lb concrete canoe displacecompared to an ultra-lightweight 38 - lb Kevlar canoe of the samesize carrying the same load?
The 30-Mg freight car A and 15-Mg freight car B are moving toward each other with the velocities VA= 20 km/h to the right and VB= 10 km/h to the left. the spring constant on car A is k= 3MN/m.
Determine the enthalpy of nitrogen, in Btu/lbm, at 400 R and 2000 psia using (α) data from the ideal-gas nitrogen table and (b) the generalized enthalpy chart. Compare your results to the actual value of 177.8 Btu/lbm.
The standard Proctor maximum dry unit weight of the sandy clay is 17.8 kN /m3 at an optimum water content of 10%. The specification requires 95% Proctor dry unit weight at acceptable water contents ranging from 9% to 10.8%. Is the specification me..
A maximum flow rate of 6 CFS is available for a river model. This corresponds to 30,000 CFS for the prototype. What is the scale of the model in terms of the prototype size
A fisherperson, pulling on the anchor cord, causes a force on the man of F=(40i+20j-50k)N. If the cord is 30m long,determine the Cartesian coordinates of the anchor at A. Assume that cord OA is a straight line.
Write a detailed set of instructions (algorithm) for replacing the tire and inner tube on the front wheel of a ten-speed bicycle. The bicycle has caliper brakes that must be loosened unless the tire is not inflated.
A tank has two identical orifices, each 5 cm in diameter in one of its vertical sides and are situated one above the other. The upper orifice is 4 m below the water surfaceand the lower one is 6 m below the water surface.
Suppose a watershed in Athens, Georgia has 25 acres pasture (CN=70) and 50 acres wooded (CN=55). Determine the excess rainfall (in inches) and runoff volume (cubic feet) assuming the design rainfall is 25-year, 24-hour.
