(a) Draw the free-body diagrams for the entire assembly (or structure) and each of its parts. neglect friction and the weights of the members unless specified otherwise. be sure to indicate all relevant dimensions. for each problem,
(b) Determine the total number of unknown forces and the total number of independent equilibrium equations.
For any flowrate, the pressures in the pipes upstream and downstream of the reducer are expected to be related by using Bernoulli's equation where p1 and p2 are the upstream and downstream pressures and V1 and V2 are the upstream and downstream ve..
A project for constructing a Facility just started. It involves the excavation of 40 to 60 feet deep and 60 feet wide trench to house double tunnels. A 24-inch outside diameter (22.5-inch inside diamater) water line is located in the path of the t..
The circular steel plate A is used to seal the opening on the water storage tank. Determine the magnitude of the resultant hydrostatic force that acts on it. Density of water = 1Mg/m^3
The turbidity of the water ranges from 30 to 60 NTU, alkalinity exceeds 100 mg/L, hardness is about 50 mg/L as CaCO3, and the water also contains regulated synthetic organic compounds resulting from industrial discharges.
The water table is at a depth of 1 m. Compute the effective normal stress and the shear stress acting on a plane rotated 60 degrees clockwise from the horizontal at a depth of 2.5 m in this deposit.
A 6.22-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.45 m/s and its y component of velocity is -2.88 m/s. (a) What is the kinetic energy of the object at this time
A trapezoidal channel has a bottom width of 5 feet, a slideslope (horizontal:vertical) of 2, and a depth of flow of 4 feet. The elevation of the channel bottom drops 2 feet every 1000 feet of horizontal distance traveled.
Given: elastic modulus of steel is 200 GPa, yield and ultimate tensile strength of steel are 600 and 750 MPa, respectively.
An investor has invested $250,000 in a new rental property. Her estimated annual costas are $6,000 and annual revenues are $20,000. What rate of return per year will the investor make over a 30-year period ignoring the salvage value
The project involved rapidly placing 5 m of fill over a large area that applied a stress of 100 kPa to the underlying soil. It was initially expected that after 2 years consolidation would be complete.
What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
A stream conveying a flood peak of 50 m3/s (velocity 1.25 m/s and depth 1 m) is divided into 1 km long reaches for solution of the unsteady equations. Determine the largest value of ft for which the solution will be stable.
