1.Calculate the force in each member of the loaded truss. (P = 2 kN and ? = 40°) Solve this problem by the method of joints. Neglect the weights of the members compared with the forces they support unless otherwise indicated. (Use plus for tension and minus for compression.) like 4/6 out of the 7 edition engineering mechanics book except p is at point e
2.List the series of steps involved in converting rural land into development. You may refer to an example of local conditions in your reference jurisdiction or you may use a description of such steps that you find from other sources, but do not limit yourself to examples in the United States.
Let X be a random variable defined by the density function f(x) = 3X^2 0
An HSS 10×8×3?16 is used as a compression member with one end pinned and the other end fixed against rotation but free to translate. The length is 12 feet. Compute the nominal compressive strength for A500 Grade B steel
the water tempearture is 10 degree celusis. how fast must the paddle wheel rotate in that compartment to generate a G(velocity gradient) value 30 s-1
Estimate the amount of Ca(OH)2(s) leached from concrete during a one-year period by precipitation. Assume that the area receives 40 in/yr of precipitation which is in equilibrium with PCO2= 10^-3.5 atm and [SO42-] = 10^-4 M.
A rectangular channel carries a discharge of 2.00 m3/sec per meter of channel width over a weir crest that is 1.4 m in height. The energy grade line upstream of the weir measure 2.7 m above the channel bottom.
Aerotron Electronics is considering purchasing a water filtration system to assist in circuit board manufacturing. The system costs $40,000. It has an expected life of 7 years at which time its salvage value will be $7,500.
Determine the ASD reference and adjusted design values for the following members and loading conditions. All members are Select Structural Southern Pine and are fully braced to prevent lateral torsional buckling. Bending Occurs about the strong axis.
The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in.
A W14x68 section of A992, Grade 50 steel, is used as a steel column with a total unbraced height of 12 ft. The column ends are both fixed. Determine the maximum axial LRFD safe load for this column
Write down a mass balance expression for a chemical release in a lake given the following: the lake is completely mixed, in-flow and out-flow are equal, degradation of the chemical is occurring through biodegradation (k1) and chemical transformati..
A company facing an interest rate of 8% must choose among projects offering the following four-year cash flows. If the company is employing the net present value criterion, which project should they choose
The flow is fully developed and laminar. Make use of the Navier Stokes equation to determine the relationship between the discharge and the other parameters involved, for the case in which the change in pressure along the channel is zero.
