Determine the minimum horizontal force necessary for 200 lb man to scale crevice (using his feet and back). The coefficient of static friction between his shoes and his back against the wall is 0.4.
The beam ABC of length L has two different moments of inertia (2I in AB, I in BC) and a constant elastic modulus E. It is fixed at point A has a roller support at point B and a load P at C. a. Sketch the deflected shape of this beam.
Design a square column footing for a 18-in square tied interior column that supports a dead load D= 220 k and a live load L=180 k. The column isreinforced with eight bars, the base of the footing is 4 ft below grade
Let us pretend you are an earthwork construction control inspector and you are checking the field compaction of a layer of soil. After compaction in the field, the density of soil was checked by excavating part of the compacted soil
determine the minimum length of a 5/16 inch, side fillet weld that will be necessary if the plate is subjected to an axial stress of 20 ksi . use an allowable shearing stress through the throat of the weld of 21 ksi.
assuming that the contaminant travels mainly by advection, propose any operational changes to the given layout to prevent the river from being contaminated.
Dispute in largest open-pit copper mine, My recollection may be skewed, so for our purposes, consider this example a hypothetical, but this is my recollection of a real case. In the early 80s, in Salt Lake County, Utah, a dispute arose involving t..
Using the method of lee et al. predict the temperature required in an isothermal plug flow incinerator to reduce the xylene level in a waste gas from 1000 ppm to 10ppm. Assume a residence time of 0.7 sec.
Create a MATLAB program and flowchart which will allow the user to input an unknown number of temperatures, each of which might be a temperature in Celsius, Fahrenheit, Kelvin, or Rankine, and will convert the user input temperature to each of the..
Diameter of the hose and the nozzle are .25ft and .1ft respectively. If the pressure inside the hose is 60 psig and the flowrate is 1.2 ft^3/s, calculate the horizontal force required to hold the hose in place.
The cash flow of alternatives J and K is shown below. If the interest rate is 10% per year, which alternative should be selected. Perform a Present Worth analysis.
The blade height is 1.0 m, and the inlet radius of the rotor is 7.0 m. The flow exits the turbine in a radial direction. (a) If the angle between the radial direction and the absolute velocity at the inlet is 30o
Consider a 2D triangular element with the three vertices at 1[1,1], 2[1,2] and 3[2,2]. the displacements at these t hree points are [0.1,0.1], [0.3,0.2] and [0.4, 0.3] mm for point 1,2,and 3 respectively
