The below W33 x 130 structuraI steel beam (E = 29 Mpsi) is externally loaded as shown (5000 lb/ft distributed load and 2000 ft-lbf moment at Point A). Include the weight of the beam in ALL considerations (Hint: the above beam designation specifies the distributed weight of the beam as 130 lbf/ft of length) Required:
a. Construct and properly label the beam shear and moment diagrams. Be certain to Indicate all minimum and maximum values.
b. Calculate the deflection at Point B clearly indicating the sign of this deflection note the above coordinate system). Use the Deflection by Superposition method.
A ground level source is emitting pollution. An air sampler is located 1 km downwind and 0.5km crosswind of the source measures the concentration of the pollutant ant ground level as 10 micrograms/cubic meter.
When a plastics plant is redesigned, a tank exit is now facing the wrong direction and must be connected to a pipe of diameter D=0.2 m with a180o bend in a horizontal plane.
Assume that the wall separating the steam and seawater is 4 mm of steel, with con- ductivity of 15 W/m K, and that a maximum 5oC difference between the two fluids is allowed in the design.
A tugboat tows a ship at a constant velocity. The tow harness consists of a single tow cable attached to the tugboat at point A that splits at point B and attaches to the ship at points C and D.
Tacoma Narrows Bridge. Conduct either a qualitive and quantitive 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 this project..
Provided that the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20 Hz to about 20000Hz. Compute the wavelength corresponding to these frequencies
Cars arrive at a toll gate on a freeway according to a Poisson distribution with mean 90 per hour. Average time for passing through the gate is 38 seconds. Drivers complain of the longwaiting time.
The 2kg block A and the 5kg block B are initially at rest on the inclined plane at 20 degrees. All surfaces in this system have a coefficient of static friction of 0.6 , and a coefficient of kinetic friction of 0.4.
The engineering team at Manuels Manufacturing, Inc., is planning to purchase an enterprise resource planning (ERP) system. The software and installation from Vendor A costs $380,000 initially and is expected to increase revenue $125,000 per year ever..
During a snowstorm the fluoride feeder in North Bend runs out of feeder solution. The rapid mix tank is connected to a 5-km long distribution pipe. The flow rate into the rapid mix tank is 0.44m^3/sec, and the volume of the tank is 2.50 m^3.
