A concrete box girder bridge has the rectangular x-section. The box is prismatic and considered thin-walled. It span is L=48m and simply supported at points A,B,C and D. The supports are assume to be able to transfer tensile forces. Diaphragms(x-beams) have been constructed at AB and CD to transfer the support reactions into the hollow x-section. Support A undergoes a settlement as a result of which a torsional moment is induced in the beam. The maximum shear stress due to this torsional moment is 1N/sq. mm. Use G=13.5GPa for shear modulus.
1.Determine the torsional moment in the hollow x-section2.Determine the settlement of support A.3.Determine the support reactions due to the settlement of support A.
a rectangular clarifier with a length:width ratio of 3:1 receives a flow of 850m3/day. the clarifiers depth is 4.0m and the detention time of the water inthe clarifier is 2.4 hrs, what are the surface overflow rate and the horizontal flow through ..
if the enginer is mounted floatiing on very weak spring, what is the amplitude of the vertical vibration of the engine? (b) if the engine is mounted solidly on a rigid foundation, what is the alternating force amplitude transmitted? Assume the con..
Assuming a standard driver reaction time of 2.5 seconds, what is the probability that the vehicle pulling out will get in an accident with oncoming traffic?
Consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam. Assume, length L, flexural stiffness EI, and mass m.
Compare the total reactor volume required for 90% removal of the same pollutant in a CSTR system that contains a single reactor against a system that contains three CSTR reactors of equal volume in series.
Assume you are observing traffic in a single lane of a highway at a specific location. you measure the average headway and average spacing of passing vehicles as 3 seconds and 150 ft, respectively. calculate the flow, average speed, and density of..

A gas occupise 250 ml and it's pressure is 550mm Hg @ 254C how many moles of gas are in this sample? (convert mm Hg to atm).
for this purpose replace this force by its equivalent of two forces at At Ft parallel and Fn perpendicular to the beam. Determine Ft and Fn.
Calculate the largest tolerable internal crack length for a 7075-T651 aluminum alloy component that is loaded to a stress one-half of its yield strength without catastrophic fracture. For the alloy, the plane strain fracture toughness is 24 and yi..
Two strips of a plastics material are bonded together as shown. The average shearing stress in the glue must be limited to 1000 kpa.
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/sec)
