determine the components of the 800 lb force f along the oblique axes a and b. also, determine the projections of f onto the a and b axes
Determine the deflection of a simple uniformly loaded beam by the Ritz method,using first one term, then two terms, adn finally three terms in a sine series. Why does the coefficient of sin2piex/L vanish?
A sky diver with a mass of 75 kg jumps from an aircraft. The aerodynamic drag force acting on the sky diver is known to be Fd = kV^2, where k = 0.228. Determine the maximum speed of the free fall for the sky diver and the speed reached after 100 m..
Wastewater is discharged into an aquifer. This wastewater contains 0.1 ppm atrazine (a common herbicide). The MCL of atrazine is 5 ppb, the density is 1.19 g/mL and the solubility is 50 ppm. 500 ft away from the plant effluent there is a permeable..
Why is granular activated carbon(GAC) used to treat the industrial wastewater stream but not the domestic wastewater stream
Compute points on the velocity profile from the pipe wall to the centerline of a 3/4-in Type K copper tube if the volume flow rate of water at 60 degrees F is .50 gal/min.
Determine whether these conditions are true or false.
How much differential settlement is causing the additional stress of 4,000 psi in girder that is rigudly attached to columns at either end of its 50-ft span. The moment of inertia of the beam is 15,000 in4, and it is a 24-in.-deep beam section.
A hyetograph has a uniform rainfall intensity of 1.5 in/hr in the first hour, 2.0 in/hr in the second, and 0.75 in/hr in the third. Calculate the direct runoff (in inches) using the SCS method. Assume a curve number of 65.
If clean groundwater flows through an aquifer contaminated with a dense non- aqueous phase liquid (DNAPL), calculate the concentration of DNAPL in the water as a function of time if the DNAPL is dissolving into the water at a rate of k1
Truck B has an 8000-lb single axle and a 43,000-lb tandem axle. On a flexible pavement with a 3-inch hot-mix asphalt (HMA) wearing surface, a 6-inch soil-cement base, and an 8-inch crushed stone subbase, which truck will cause more pavement damage
A 10cm diameter vertical tank holds 20cm of water topped with 15cm of ethyl alcohol. The cylinder is rotated about its central axis at a rotation rate of 20 rad/s. (a) What will be the shape of the air-alcohol and alcohol-water interfaces
Consider a cantilever beam with a trapezoidal load along the length, a concentrated load at its free end, and an applied moment at the mid-span of the beam. What is the moment at the free end of the cantilever
