Two pieces of steel are held together with six bolts. One end of the first piece of steel is welded to a beam and the second piece of steel is bolted to the first. There is a load of 54,000 pounds applied to the end of the second piece of steel. The tensile strength of steel is 74,000 psi, the shear strength is 48,000 psi.a) Calculate the diameter of the bolts needed to support the load.b) Find the width of the steel if the thickness of the steel is 1/4Â?. The bolt holes are 1/16Â? larger than the bolt.
The saturated unit weight (sat) of the sand is 20.0 kN/m3 and the anticipated depth to water in the well during pumping is 20 m below ground surface.
At a given initial time, the pressure in thetank is 100 kPa gage, and the atmospheric pressure is 100 kPaabsolute. Some time later, after more gas is pumped into thetank, the pressure in the tank is 200 kPa gage, and the temp.
Use this information to estimate the demensions of the biofilter needed to treat 10,000 m^3/hr of air (at 30 C and 1 atm) containing 200 ppm styrene being emitted from a boat- manufacturing plant.
How much differential settlement is causing the additional stress of 4,000 psi in girder that is rigudly attached to columns at either end of its 50-ft span. The moment of inertia of the beam is 15,000 in4, and it is a 24-in.-deep beam section.
The length of a reading room in a library is 10 m and its breadth is 8 m. Compute the distributed live load, assuming the basic value of the load to be 2873 N/m2.
Find an equation that expresses the relationship between the wages earned (x) and the Social Security taxes paid (y) by an employee who earns less than the maximum taxable wage base.
An elbow, 90 degrees smooth bend flanged, is used in the Alaskan pipeline. Inside pipe diameter is 48 inches. Flow is 1.6 million barrels a day. 1 barrel=42 gal. Velocity is 8.27 ft/s. SG=0.93
Use modern software tools to analyze a structural system of a building.
IT IS DESIRED TO RETRACE THE LINE WITH A COMPASS TODAY, WHEN THE DECLINATION IS 5 35'E. WHAT READING OF THE COMPASS SHOULD BE USED TO RETRACE THE LINE
(a) Determine the desired diameter of the disk. (b) If the rubber strain is not to exceed 0.2 in/in, determine the maximum allowable compressive force. Recall that the spring constant, k=Fx,or in terms of an axially loaded member
For the beam shown be low, derive the equation of motion in the ∞- and y-directions. Recall that the deformation of a bar along its axis
To verify the constant of a particular prism, a straight line EFG is laid out. The EDM instrument is first set up at E, with the following measurements recorded: EG = 426.224 m, EF = 277.301 m.
