Question 1:
i. With the aid diagram / picture, briefly explain about the function of bridge component below:
a. Anchorages
b. Bridge Pylon / Bridge Tower
c. Foundation
d. Pier
e. Hanger
f. Suspension cable
ii. Explain the advantages and disadvantages of suspension bridge compare to cantilever bridge
iii. A critical problem in the design of any cable structure is the dynamic effect of wind, which causes an undesirable fluttering of the structures. Suggest a few methods to stiffen the cable against motions due to moving or changing loads.
Question 2:
Determine
i. The force P needed to hold the cable in the position shown, i.e, so segment BC remains horizontal.
ii. Compute the sag yB and the maximum tension in the cable.
iii. Calculate the total length of cable AE
iv. Determine the size of the cable, if the allowable stress of the cable is 22.5 MPa
A Bonda portable generator is powering a small travelling fridge (120V) in your RV and consumes 125 watts. The efficiency of the generator's gas motor is 23% and the electrical portion (power head) is more efficient at 91%. If white gas weighs 6.073 ..
In order for a shower head to produce a 2.5 gpm flow for 120?F water, what pressure (psi) is needed at the hot water tank if the shower head elevation above the hot water tank is 28 ft? The pipe diameter is 1-in, and assume that the shower head has a..
an electrical-generation utility sometimes pump liquid water into an elevated reservoir during periods of low electrical consumption. this water is used to generate electricity during periods when the demand for electricity exceeds the utilities a..
The house has a dirt-floor crawl spaces (1m high). The emission rate of radon into the crawl space is 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space
write a c++ code for two classes one being automobile and one being motorcycle both being the base class then at least one derived class from each
A conventional consolidated drained (CD) triaxial test is conducted on sand. The cell pressure is 100 kPa, and the applied axial stress at failure is 200 kPa.
The probability density function, f(t), of the time in hours between storms during the summer in Miami is estimated as f(t) = .014e^(-.014t) if x > 0, f(t) = 0 if x is less than or equal to 0 where t is the time interval between storms in hours.
On a certain highway a -6% grade meets a +2% grade at station 70 + 00, elevation 550.97 ft. An equal tangent vertical curve, 800 ft. long, is to be installed to connect these two grades.
a) What flow rate (m 3/s) does the filter handle during production? b) What volume of water is needed for backwashing plus rising the filter in each filter cycle?
The specific heat capacity Cp of the process fluid is not known at the mean bulk fluid temperature but is a linear function of temperature, and must be calculated using the following information, Cp at 300K is 1.98 kJ/kgK, and Cp at 400K is 2.65 kJ/k..
Design a 3-meter cantilever slab to carry a uniform total dead load of 8.2KN/m2 and a concentrated live load at the free end of 30 KN/m. f'c=28Mpa fy=420Mpa.
