A beam of negligible mass is supported by two cables when a load P is applied. If P is 100 Ib, find the tension in the cables, their elongation, and the minimum thickness of the beam if it is to be made of aluminum.
A concrete mix with a 3 inch slump, w/c (water content) ratio of 0.50, and sand with a fineness modulus of 2.4 contrains 1700 lb/cubic yard of coarse aggregate. Compute the required weight of the coarse
One cubic meter of nitrogen at40oC and 340 kPa iscompressed isoentropically to 0.2 m3. Calculate the finalpressure and temperature when the nitrogen is reduced to that volume.
assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m length of dam.
Is the system within membrane manufacturer's warranty requirement of maximum flux rate of 14 gfd? What is the annual power cost of the RO system?
The design wind speed is 15 mph at T=10C and p=0.9 bar. The efficiency of the turbine is n=20% meaning that 20% of the kinetic energy in the wind can be extracted. estimate the power in watts that can be produced by the turbine.
If the flow that you determined in (b) occurred as rainfalluniformly over the earth's surface, what would be the mean annualrainfall (cm/y)?
The column bearing is 12 in. measured along the beam, and the bearing plates at the end supports are each 8 in. Investigate this beam of A992 steel for (a) flexure, (b) shear, and (c) satisfactory transmission of the reactions load
A block of material has a mass density of 650 kg/m^3 and volume of 0.37 m^3. Find the weight of the block in Newtons and the specific gravity of the material. What downward force (in Newtons) would be necessary to hold the block from the previous pro..
If the free surface at a distance from the axis of the vortex, which is sufficient for its effect to be negligible, is 180 mm above datum, what will be the height above datum of a point B on the free surface at a radius of 100 mm
A mixture by volume of 50% hydrogen and 50% carbon dioxide is flowing isentropically through a nozzle with flow rate of 1 m^3/s measured at inlet condition of 700 kpa and 373k the inlet velocity is negligible and the mixture expands to a pressure of ..
