An S 12x40.8 of A36 steel in a building is supported as a simple beam having a span equal to 17ft 6in. and carries a uniform load equal to 1.60 klf, which includes the weight of the beam over the entire span. A) Compute the maximum fiber stress. B) If the compression flange of the beam is supported laterally only at the ends of the span, what will be the allowable compressive stress in the extreme fibers?
Given that uniform flow is subcrital and there is a weir in a rectangular channel, how do you determine what the weir height should be to force the flow to be critical. Draw this transition on a specific energy curve.
A closed system of 0.123kg undergoes a frictionless, quasi-static process along the path PV=C from 100kpa to a final state where the volume is twice the initial volume.
Consider your cooking gas contains 80% propane and 20% butane. While burning on a cooktop, assume it burns with 200% excess air. If no heat is lost, determine the maximum possible flame temperature.
Radon from well water may pose a radiological health hazard. One treatment technique is simply to hold the water in storage, allowing the radon to decay. how large must each be to achieve the desired level of control.
If the hydraulic head in the canal is 100 ft and in the drainage ditch it is 80 ft calculate the maximum mounding height and the mounding distance from the canal that will occur if the farmer irrigates at a rate of 2 acre-ft/acre/year.
A tray rests on an extendible arm consisting of two steel tubes with two different outer diameters. The downward force at the tray center F0 = 1000 N. Determine the downward deflection of the tray center and the tilt angles of the tray about each ..
Suppose there were reason to believe that incomes in some population were normally distributed, with a mean of $47,000 per year, and a standard deviation of $5,500 per year.
Given that the moduli of electricity of this material are respectively 69GPa and 393 GPa plot modulus of elasticity versus the volum percent of Al2O3 in Al from 0 to 100 vol % using both upper and lower bound expressions
Property taxes,insurance and storage will run 5%.What is the owning cost for the dozer?Use the time value method to calculate the depreciated portion of the ownership cost.
A single-scoop ice cream cone is a composite body made from a single scoop of ice cream placed into a cone. Assume that the scoop of ice cream is a sphere with radius r=1.45in that is placed into a 4.00in tall cone.
The viscosity of the film of oil separating the piston from the cylinder is 0.020 lb.s/ft. Calculate the force required to maintain this motion.
The left-hand span is 16 ft and the right-hand span is 20 ft. The beam supports a uniform load of 900 plf, which includes its own weight, over the entire 36 ft and also a concentrated load of 10,000 lb applied at a point that is 5 ft from the left..
