Explain which type of survey will you recommend in muddy area and why?


1-) Homework solution should be made legible in your own handwriting. Unreadable ones are considered false. Upload your homework solution to the system with pictures of the papers that you wrote handwritten properly. Blurred, curved, half, etc. before loading. Pay attention to not be. Assignments that cannot be read for such reasons will be invalid. 2-) The result of each transaction will be written up to 7 digits after the comma. Calculations will be checked accordingly, 3-) If the process and results are not synchronized, no points will be awarded. In other words, if the action you made does not lead to the result you have found, or if the result you wrote is not reached with the transaction you have made, the solution will be wrong and no points will be awarded. There is no grade for the departure. In short, you can get points if both your path and result are correct. Good luck.


A concrete dam retains water to a depth of 18m. The face of the dam in contact with water is vertical for the first 6m and there after it is inclined at 12° to the vertical in order to increase the thickness of dam towards the base. Determine the magnitude and direction of the resultant water pressure per meter length of the dam and depth of its point of application on the face of the dam. If the concrete weigh 23.55KN/m³, determine the point of application of the resultant of the water pressure and weight of the dam on the base of the dam.

Design wall footings for the values given below:Weight of reinforce concrete: 150 lb/ft3Weight of plain concrete: 145lb/ft3Weight of soil: 100 lb/ft3Wall thickness: 12 in.D = 17 k/ft L =25 k/ft f’c= 4 ksi fy= 60 ksi qa= 4 ksf Distance from bottom of footing to final grade = 4 ft.
A small engine has been mounted on a structural system. The engine will run at 1800rpm with an unbalanced massof 28.5*10^-3kg at a radius of 0.15m.The structure has a vertial stiffness of 86.7KN/m. A free vibration test has been run to estimate the damping when the engine till for the firt 21st oscillations. The test measured of a frequency of oscillation f 15Hz and a ratio of amplitude f 22.0. What vibration amplitude will the system have with the engine running at full speed?
Consider a mercury manometer connected to a tank of water, as shown in the diagram below. Please calculate the ratio of hm to hw. (The specific gravity of mercury=13.56)
