The composite beam shown is fabricated by connecing two W6 x 20 rolled-steel members, using bolts of 5/8 in. diameter spaced longitunally every 6 in. Knowing that the average allowable shearing stress in the bolts is 10.5 ksi, determine the largest allowable vertical shear in the beam.
H = h - N Point B has a geoid correction of -100', and a NAVD88 elevation of 100'. What is the point B ellipse height
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa. The washer dimensions are as follows: hole diameter is 27 mm. outside diam..
For determining the centroid of the area, two square segments are considered; square ABCD and square DEFG. What are the coordinates (x, y ) of the centroid of square DEFG?
Air pollution in a city is caused by the following four sources: vehicle exhaust (V), industrial exhaust (I), dust (D), and pollen from plants and trees (T). On a particular day, the likelihood of air pollution caused by these sources is 4:3:2:1, ..
Assuming constant acceleration, determine how long the train blocked the crossing. Dis- regard the width of the crossing.
Oil (specific gravity 0.752) flows through a 6" horizontal pipe under a pressure of 60 psi. Assuming no losses, what is the flow in cfs if the pressure at a 3" diameter reduction is 20 psi
An entrepreneurial new civil engineering graduate started a lab for testing endocrine disrupting compounds. The lab just broke even the first year, but in years 2 through 5, it made a profit of $97,000 each year.
calculate departures and latitudes, misclosures in departures and latitude, and traverse relative precision. Balance the departures and latitude using the compass rule, and calculate coordinates of points B, C, and D.
A lagoon with a volume of 1200 m^3 has been receiving a steady flow of a conservative waste at a rate of 100m^3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10mg/L.
air flows through a horizontal iron tube (e=0.15m) at Q=5.7x10-2 m3/s. find the pipe diameter if the pressure drop is 3.5kPa per 30.5m of pipe. air density = 1.23kh/m3 dynamic vicosity = 1.79 x 10-5 N.s/m2)
over the range of cylindrical parts manufactured on a computer-controlled lathe, the standard deviation of the diameters is 0.002 millimeter/ (a) what does Chebyshe's theorem tell us about the probability
an equal-tangent sag vertical curve is designed with the PVC AT STation 109 + 00 and elevation 950 ft, the PVI at station 110 + 77 and elevation 947.34ft,and the low point at station 110 + 50 . Determine the design speed of the curve.
