Consider the two loading scenarios on the beam, where the beam is supported by a pin joint on the left and roller joint at the right end. What are the internal forces and moment at point A for each
Emissions of heat-trapping carbon dioxide (CO2) reached an all-time high of 31.6 gigatons in 2011, a 3.2% increase over 2010. The International Energy Agency said this further reduces the chance tha
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar
The tank has an inner diameter of 1.5 m and a wall thickness of 18 mm. If the pressure in the tank is p=1.20MPa, determine the force in the 16 bolts that are used to attach the cap to the tank. Also
The barrel has an inner diameter of 4ft. Neglect its wall thickness. Assume that only the hoops resist the water pressure. Note: Water develops pressure in the barrel according to Pascal's Law, p=62
Determine the normal stress in a soccer ball if the internal pressure is 110 kPa, the outside diameter is 220mm and the wall thickness is 3mm .
Typical water supply at a faucet in any building is conveyed in copper pipe that is ½" in inside diameter, with a wall thickness of 0.040". If the water pressure is 50 psi and the valve is cl
Often times, this pressure comes from the fact that community's water supply is stored in an elevated reservoir. Determine how high an elevated reservoir must be so that the water supply has a press
Water flows past a triangular flat plate oriented parallel to the free stream as shown. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume
An airplane flies at a speed of 360 mph at an altitude of 5000 ft. If the boundary layers on the wing surfaces behave as those on a flat plate, estimate the extent of laminar boundary layer flow alo
In each experimental run, the concen tration of free available chlorine was varied and the time required to kill 99% of the organisms was determined. The results showed that a CT value of 200 min mg
Calculate the relative velocity of a solute front that is flowing through an aquifer. The organic carbon partitioning coefficient (Koc) is 6 mL/g and the friction of organic carbon in the soil is 2%
A geothermal power uses hot water (185oF) as a heat source and the cold water from a close by lake (60oF) as a heat sink. The basic operating system is a close loop ammonia efficiency of the cycle t
The dissolved oxygen of sample water is 1.5 mg/L. At 25 C, the dissolved oxygen of the dilution water is 8.25 mg/L. You are told the BOD5 of the sample is 130 mg/L. You have a target final dissolved
Ten tons of a mixture of paper and other compostable materials has a moisture content of 7%. How many tons of water must be added to the solids to achieve a mixture with 50% moisture for composting
At a certain location on the surface of an engineering component, the material is in a state of plane stress with principal stresses of fmax = 150 MPa and fmin = 50 MPa (both tensile). If the yield
A MIPS-based computer system with 2 GB of main memory that is built on a single circuit board. It is designed with a single control signal between the CPU chip and main memory, i.e. one bit of contr
explain in your words the procedure of the Gauss-Newton method used to control some parameter (z) to meet some expected performance (y) using controllable parameters (A,B)
Trips can be classified by productions/attractions or origins/destinations. Which classification provides the direction of travel. Describe the product/outcome (e.g., production-attraction matrix) a
At a certain location along the span, a reinforce concrete beam section with d=14 in. and b=10 in. is subject to a design shear of Vu=50k. Using No.4 stirrups, compute the required stirrup spacing a
The setting velocity of a particle is 0.002 m/s and the overflow rate of a settling tank is 0.008 m/s. (a) what percent of the particles does the settling tank capture. If the particles are flocculat
Find the area of steel reinforcement required for a concrete T-beam for the following data; f'c = 3 ksi, fy=60 ksi,d=18 in, t= 4.5 in., bw= 10 in., bf= 36 in., 3/4" aggregate, and the section sustai
A 4 mgd water treatment planet is being designed for an overflow rate of 0.5 gpm/ft^2. If two circular sedimentation basins will be used at al times, what should be the diameter of each basin
A single-scoop ice cream cone is a composite body made from a single scoop of ice cream placed into a cone. Assume that the scoop of ice cream is a sphere with radius r=1.45in that is placed i
The emission rate of radon into the crawl space is reported to be 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space. The outdoor concentration of
