Q6: A cantilever beam having span ‘L’ m was subjected to a uniformly distributed load of
magnitude 8 kN/m for a distance of ‘0.6 L’ from the free end and two concentrated loads one of
magnitude 15 kN at a distance ‘0.25 L’ m from the free end while the other of magnitude ‘22’ kN at
a distance ‘0.6 L’ m from the free end respectively. It was observed that the maximum bending
moment acting on the beam is equal to (-369 kNm). Suggest a suitable span for the beam based on
the loading condition. How it will change the reaction at the fixed support? What happens to the
shear force and bending moment values at the fixed support, free end and at the center of the
beam? By plotting bending moment and shear force diagram for the beam briefly conclude the
relationship between the values for shear force and bending moment

Consider a typical settling tank of 10 m diameter and 10 m height. Inlet pipe is approximately 2 m deep from the top of the tank. Perform following preliminary calculations. a. For a water-sand flowrate of 1500 m 3 /hr with 1000 ppm of sand, calculate sand particle size than can be settled in the tank. (Water: density = 1000 kg/m3 , viscosity = 1 cP; Sand: density = 2500 kg/m3 ) (6-marks) b. Consider settling of different sizes (50, 100, 200, 300 µm), calculate required tank size for settling of each particle size at a constant inlet flow rate of 1500 m3 /hr. (4-marks) c. Now consider settling of 50 µm size particles in the tank with diameter of 10 m and height of 10 m, calculate inlet flow rate required, (2-marks) d. For fine particles ( 50 µm), if tank size required to operate at 1500 m3 /hr is very large, suggest design modification to settle the fine particles. (4-marks)

Using the rational method, determine the amount of runoff that would occur for a paved parking lot that is 100m * 50m and is uniformly sloped from one long edge to the other long edge at a rate of 2%. The time of concentration for this parking is 4 minutes. The five-year storm with duration of 4 minutes has an intensity of 10 mm/hr. The runoff coefficient for this parking lot is 0.80.آ [Q=0.166 CIA]
The runoff from part (a) is to be contained in a trapezoidal drainage ditch with the following properties: side slope = 2m horizontal run for every 1 m rise, width of invert = 2m, longitudinal slope = 0.005 m/m, and Manning's number = 0.08. If the maximum permittedآ depth of water is 100 mm, using Manning's equation for open channel flow, determine if the ditch will be able to accommodate the flow in part a

You are planning to excavate the 30-foot by 40-foot basement area of a house to a depth of 10- feet in common earth. An 18-inch wide, 5-foot deep, 100-foot long sewer trench will also be required. You have at your disposal a hydraulic excavator with a ½ cubic yard 24-inch wide bucket. The excavator’s maximum digging depth is 14.7-feet and the average angle of swing is estimated to be 75-degrees. Job efficiency is expected to be 45-minutes per hour with costs for the excavator being $50 per operating hour and $250 each to transport the excavator to the site and return it to the equipment yard after trench and basement excavations are complete. Allow for 5-percent overage in basement excavations and 10-percent overage beyond the capabilities of the equipment for the trench. After the foundation has been placed and backfilled, and the trench has been covered, it is estimated that 400 cubic yards of loose material will remain in a single stockpile that will need to be moved offsite. You will have at your disposal a crawler crane with a 0.90 LCY clamshell to load a series of dump trucks. Cycle time for the clamshell is estimated to be 45-seconds with the same 45-minute per hour efficiency. Costs for the crane and clamshell are $75 per operating hour and a combined lump sum of $500 to mobilize and demobilized.

ASSUMPTION(S)/CONDITION(S)  Excavator bucket heap accounts for material swell. You do not need to account for swell and/or shrinkage in your calculations.

 When using tables to determine appropriate factors to use in your calculation and a range is given, use the middle value between the high and low.

 All material excavated for the trench will be used during backfilling operations. There are no spoils remaining from the trench portion of the excavation.

 Assume that sufficient dump trucks will be available into which to load the remaining basement spoils. That is, there will be no downtime waiting for trucks to become available.

 No partial workdays are allowed. Should less than a full day be required to all or a portion of the work, payment for the full 8-hours is still required.
