1.Computations are to be made for a street curve with delfection angle delta = 50 degrees 00 minutes 00 seconds and centerline radius of 120 feet. The PI is at station 8+72.43. Calculate the deflection angles and chords to stations 8+25, 8+50, 8+75, 9+00 and 9+21.19
2.IF the bulk density of coarse grained soil is 1760 kg/m^3 what is its void ratio, e, and saturation, S? Draw the complete phase body diagram and show the masses and volumes.
3.Knowing that each of the shafts AB, BC, and CD consists of a solid circular rod, determine (a) the shaft in which the maximum shearing stress occurs, (b) the magnitude of that stress.
an apple weighs 60g and has a volume of 75cm^3 in a refrigerator at 8 degrees C. What is the apple's density List three intensive and two extensive properties of the apple.
Water enters the lock of a ship canal through 180 ports, each port having a 2 ft by 2 ft cross section. The lock is 900 ft long and 105 ft wide. The lock is designed so that the water surface in it will rise at a maximum rate of 6 ft/min.
A long line of burning agricultural waste emits 0.3 g/m/s of particulate matter on a clear fall afternoon with winds blowing 3 m/s perpendicular to the line. Estimate the ground-level particulate concentration 400 m downwind from the line.
Determine whether these conditions are true or false.
The volume of the system is doubled from 1 m^3 to 2 m^3 while 200 kJ of heat is added to the system. If no work is done except for the boundary displacement work and the pressure remains constant at 101.3 kPa (1 atm) throughout the process,
Suppose X is a continuous random variable with probability density function, f(x)=4x^3 for 0
Structural steel beams are to be placed at 7ft 6in on center under a reinforced concrete floor slab. If they are to support a service dead load D=64 psf of floor area and a service live load L=100 psf of floor area
Determine the peak outflow rate when the inflow hydrograph is routed through this basin and what is the design storage and water surface elevation at the peak outflow rate.
A stream is in equilibrium with atmospheric oxygen upstream of a waste outfall. The waste outfall creates a BODo of 20 mg/L in the stream. The k(BOD) is 0.4 /day and the k(o2) is 1.4 / day. The stream temperature is 15 degrees Celsius.
Conduct either a qualitative or quantitative risk assessment on this project. Identify the risk factors that you consider most important for the suspension bridge construction. How would you assess the riskiness of the project? Why?
