1. The T-beam shown below is made of regular weight concrete (specific weight 150 lb/ft3 (pcf)). Determine the dead load per foot length of the beam in pounds per foot (plf). Neglect the weight of the steel reinforcement.
2. An 8-ft high building wall consists of 12-in. clay-brick and 2x4 unplastered wood studs on both sides. Determine the load the wall exerts on the floor in pounds per foot (plf) length of wall.
3. The second floor of a light manufacturing building is constructed from a 5-in. thick stone concrete slab with a 4-in. cinder fill topping (see the figure below). If the suspended ceiling of the first floor consists of metal lath and gypsum plaster, determine the dead load for design in pounds per square foot of floor area.
4. Determine the reactions on the beam. The support at B can be assumed a roller; support at A is a pin.
5. Determine the vertical reactions at the supports A and B. Assume the support at A acts as a roller and the connection at B is a pin.
6. Determine the reactions on the beam. The beam has pin support at A and roller support at B. Note that the support at B is bearing against a sloping surface as indicated in the figure.
A well water has the following mineral contents in mg/L: Na+=20; K+=35; Ca+2 =15; Mg+2 =10; Sr=0.5; Cl- =40; HCO3- =65; CO3-2=5; SO4-2=15; and NO3=10.
List the forces and moments that must be in balance to sustain an aeroplane in steady, straight and level flight.
Calculate how many chlorine atoms will be in an average neoprene chain? b) Sketch the bonding between polychloroprene chains due to sulfur linkages as neoprene is vulcanized into an elastomer. c) You decide to go swimming in Bear Lake in late Novembe..
Calculate the required area of an air to air heat exchange to cool 20,000 cfm from 1200 F to 400 F. Assume ambient air at 80 F will be heated to 800 F by the exchange.
The long-term average January precipitation in the Colorado River basin is 1.11 inches, with a standard deviation of 0.60 inches. Assuming a normal distribution, what is the probability that less than 0.5 inches of precipitation will occur in any ..
At an excitation frequency of 4 Hz, the response tends to increase without bound(ie a resonant condition). Next, a weight of deltaW= 5lb is attached to the mass m and the resonance test is repeated.
Batteries in a flashlight must be held in electrical contact even though the outer plastic housing expands differently than the battery and terminals. This is accomplished by having a compliant spring compressed as the cover is screwed on the flashli..
A trapezoidal channel is to be excavated in alluvial material on a bed slope of 1:10000. The side slopes will be 1(vertical) : 2(horizontal). Details of the bed material are as follows: Particle diameter 4 mm
They completed the installation when the temperature was 20 degrees Celsius. When the temperature rose to 25 degrees Celsius, the rail buckled into an isosceles triangle because they had not left an expansion gap.
Nighttime traffic on a single lane of rural highway is light, with a flow of 40 vehicles/hour , and is well described by a Poisson arrival process.
The dimensionless henry's constant for TCE at 25 degrees celsius is 0.4. A sealed glass vial is prepared that has an air volum of 4mL overlying an aquesous volume of 36mL.
Two smooth circular cylinders of weight w=500N and radius r=200mm are connected at their centres by a string AB of length 600mm and rest upon a horizontal plane.
