A column is to support a statue concentrically that weighs 200 kN. The cross section of the column is a regular hexagon with a hole in its center. The diameter of the hole is 75mm. If the stress in the column is limited to 250 MPa, what is the measure of one side of the hexagon? Answer should be in mm.

i: A hydraulic shovel with a bottom-dump bucket with a heaped bucket volume of 5 m3 is excavating tough clay. The swing angle is 47 degrees and the job efficiency is 0.86. Calculate the shovel production in BCM
ii: Estimate the time required to load 452 m3 of gravel from a stockpile into trucks using a clamshell having a heaped bucket capacity of 0.57 m3. The estimated cycle time is 20s. Swing depth factor = 1.0. Job efficiency is estimated to be 51min/h.
iii: A small hydraulic excavator will be used to dig a trench in hard clay. The trench size is 0.76 m wide by 1.52m deep. The excavator bucket available is 0.76 m wide and has a heaped capacity of 0.51m3. The maximum digging depth of the excavator is 4.90 m. The average swing angle is expected to be 75° and the job efficiency is 71 %. Estimate the hourly trench production in BCM and in linear meters of a trench.

A.
increase
B.
decrease
C. not affect
In what case the concrete can benefit from the high heat generated
during hydration process? And what case the high heat will have
negative effect on the concrete?

A small village is located near a stream which is to be used as the source of water supply for
the community. The minimum flow in the stream is 550 m3/h. The population analysis
reveals that the population is expected to increase linearly from a population of 10,000 in
2008 to 30,000 in 2058.
The water consumption of the community is estimated to reach an annual average demand
of 300 L/capita/day, a maximum daily demand of 1.8 times the annual average and peak
hourly demand of 1.5 times the daily average.
Would you be able to supply these demands directly from the stream? If not, what would
you recommend?
a) In the year 2030
b) In the year 2058

We know that layout planning is deciding the best physical arrangement of all resources within a facility and facility resource arrangement can significantly affect productivity.
Now we also know that there is always room for improvement (Kaizen). If you are given a chance to redesign your kitchen,

Two piezometers are installed 2430 m apart in a confined aquifer. The head at the first piezometer is measured as 29.1 m and the head at the second piezometer as 26.7 m. The aquifer has a saturated thickness of 17.3 m, and hydraulic conductivity of 8x10-4 m/s, and effective porosity of 0.16.
Determine:
1.1. without any calculation, predict the direction of groundwater flow
1.2. the discharge rate through the aquifer in m3/d/m of aquifer width
1.3. the specific discharges (Darcy velocity)
1.4. the pore velocity (seepage velocity)
1.5. the time for water to travel between two piezometers in years
