A rectangular beam, simply supported over a span of 4m, is carryinga uniform distributed load of 5kN/m and a concentrated load of 5kNat the center of the beam. Find the dimensions of the beam, ifdepth of the beam is 2.5 times its width. Take maximum bendingstress in the beam section as 75MPa
a) Depth of Beam b) Width of Beam
An activated sludge process receives 4000m^3 / day containing 120 mg BOD /L from the primary settling tank and 3500 m^3/day Containing 25mg BOD/L from the secondary settling tank.
Discuss the effects of the project on the local community of the project described below 1.) The social, economic and environmental significance of the project within the local community 2.) The good, and bad impacts the project might have.
Let the lengths be 600mm and 300mm , and the angle 50 degrees . If the permitted additional elongation of the cable is 0.20mm , determine the maximum allowed distributed force per length q.
A rigid tank contains 1 kg of H20 at 100 kPa, x=0.1. Given that the tank can withstand a maximum internal pressure of 2 MPa, determine (a)the maximum temperature to which the steam in the tank can be heated,
A 10 m long built-up beam is to be fabricated from a universal section beam (UB) and two 'C' channel sections (as indicated). The beams are joined by bolts, with the allowable shear load in each bolt being 12 kN.
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
Use the Rankine cycle. The boiler operates at a 1000 kpa with a maximum temperature of 30 degrees Celsius. The condenser is isobaric and operates at -5 degrees Celsius.
A 100ft tape is calibrated at 68 degrees F, fully supported with 15 Ibs of tension and found to be 99.987 ft long. Is this tape is used fully supported with 15 Ibs of tension at 86 degrees F to measure a distance that is recorded as 136.48 ft,
What do you understand by the term durability? Compared to other considerations, how much importance should be given to durability in the design and construction of concrete structures?
An engineering student, recognizing that the "ideal gas law" requires gas velocity to be function of temperature, suggests that an easy way to increase efficiency would be to change the temperature of the exhaust gas being treated.
Calculate the overall modulus of the composite, explaining your calculations and the assumptions you have made when it is loaded:
Determine the required dimensions. The inside diameter is to be two- thirds of the outside diameter. The allowable shearing stress is 70 MPa, and the angle of twist is not to exceed 4 degree in 3 m of the shaft.
