1.In a curved prestressed bridge, how should the guided bearings in piers of the curved region be oriented with respect to the fixed bearing in abutment?
2.Design a balcony slab exposed to the weather. The cantilevered span is 8 ft and the service live load is 100 psf. fc' = 4,000 psi, fy = 60,000 psi. [Hint: Reinforcement is placed on top. For thickness of slab, in addition to the provision of the main steel and shrinkage steel, at least 3 in. of depth (cover) should exist over and below the steel.
A rectangular concrete channel is 3 m wide and 2 m high. The water 20 deg Celsius in the main channel is 1.5 m deep and is flowing at a rate of 30 m^3/s. determine the flow area, wetted perimeter, and hydraulic radius. Is the flow laminar or turbu..
A hydraulic jump occurs in an rectangular channel 2.3 m wide when the discharge is 2.5 m^3/s. If the upstream depth is 0.25 m calculate the depth downstream of the jump and the energy loss in the jump.
After a few drinks under exactly the same conditions, the driver fails to stop in time and strikes the object at a speed of 35 mi/hr. Determine the driver's perception/reaction time before and after drinking.
Explain how the presence of the collimation error, e, can be detected in a "Two Peg Test" operation.
Knowing that its speed continues to increase at the same rate until it reaches 100 km/h at point C, 1) determine the speed at point B, and 2) the magnitude of the total acceleration when t = 20 seconds.
The probability that a new car battery functions for over 10,000 miles is .8, the probability that it functions for over 20,000 miles is .4, and the probability that it functions over 30,000 miles is .1. If a new battery is still working after 10,..
Diesel fuel has an average chemical formula of C12H23 and a density of 6.45 lb/gal. Calculate how many lbs of CO2 are produced per gallon of diesel burned (assume complete combustion).
If you deposit $1000 per month into an investment account that pays interest at a rate of 6% per year, compounded quarterly, how much will be in the account at the end of 5 years
A solid steel bar of diameter 30 mm is enclosed by a steel tube of outer diameter 45 mm and inner diameter 36 mm. Both bar and tube are held rigidly at end A and joined securely to a rigid plate at end B. The composite bar, which is 500 mm long, is t..
The following data were obtained for a plate-and-frame filter of total area A=500 sq cm. operating under a constant pressuredrop of 0.1 atm: Time t (min): 50 75 100 Volume of filtrate V (liter): 9.7 12.3 14.0 The filtrate is essentially water.
A 100-ft steel tape was used in the field to measure a distance of 247.53 ft. the following data represents the conditions in the field at the time of measurement: tempreture = 41 F, tension = 30 ib, and tape supported at ends only.
a 60 -m- long steel wire must not strech more than 48mm when the tension in the wire is 6 kn. determine the corresponding value of the normal stress.
