A simply supported span of 28 feet must carry a uniform loading that produces a total factored maximum moment of 300 K-ft including the beam weight. The concrete can be 3.5 ksi and the steel is grade 60. You can design the beam as a single reinforced, double reinforced or an isolated ‘T' type beam as far as the architecture is concerned, but the beam width must be 24in.a. Sketch a shear diagram for this beamb. If the effective depth was assumed to be 14in, determine the maximum design shear force for the given loading.c. Again assuming d=14in, determine, or at least show exactly how to determine, the portion (length) of span of the subject beam which theoretically would require no shear reinforcement.
A 6-inch diameter steel sphere (sg = 8.0) is released in a large tank of oil (sg = 0.86). The terminal velocity of the sphere is measured at 13.5 ft/s. Calculate the absolute viscosity of the oil.
The perpendicular distance between two parallel tangents of a reversed curve is 20m. The azimuth of the back tangents of the curve is 270 00 and the azimuth of the common tangent is 310.
Biomass is increasingly used as a fuel to produce power and heat. A sugarcane-? processing mill is powered by a biomass power plant with 140 MW of electricity and with 60 MW of heat in the form of steam for sugar extraction from the cane.
Determine the mass and specific volume of argon gas in a vessel at 150 kPa and 20°C. The vessel is spherical, with radius 5 m.^5
A flat broad-crested regular step dam with a drop of 2 m is situated on a grossly polluted stretch of river below a sewage outfall plant. The river is located at an elevation of 2 km.
the cost and revenue associated with producing a sustainable component are fixed costs = $112,500. Variable costs = $30 / unit. Revenue = $45 / unit. How many units must the company sell each year to breakeven
Write the mass balance equation for a plug flow with a second order decaying substance,C. Solve for the steady state concentration of C as a function of the second order rate constant k, longitudinal distance x, mean velocity u, and the concentrat..
Assume you are observing traffic in a single lane of a highway at a specific location. you measure the average headway and average spacing of passing vehicles as 3 seconds and 150 ft, respectively. calculate the flow, average speed, and density of..
Calculate the compressive stress (in psi) for a 6-in diameter by 12-in high concrete test specimen if the total deformation under load is 0.015 in. Calculate the total load on the test cylinder stress.
If an additional 11-ft lane is added (each direction) and all other factors stay the same, what will be the new level of service?
Estimate the convective heat transfer coefficent for natural convenction from a horizontal steam pipe. The outside surface temperature of the insulated pipe is 80 degree C. The surrounding air temperature is 25 degress C.
A worker needs to enter a confined space to tighten the packing on a leaking argon valve. Describe two procedures that could be used to isolate the argon line and valve prior to starting work.
