1.Why is the anchorage capacity of a standard hook not increased by extending the bar well beyond the end of the hook?
2.Two solid cylindrical rods are joined at B and loaded as shown rod AB is made of steel(E=200 GPa) and rod BC of brass ( E = 105GPa) determine a) the total deformation of composite rod ABC, b) the deflection of point B.
3.What is the conclusion of T-Beam?what is the main point we should know about T-Beam?How to make the project of T-Beam become strengh?
4.Water is to be pumped along a 150mm diameter asphalted cast iron pipe at a rate of 0.9m3 /min. The pipe is 3 km long and rises 26m in this length. Calculate the frictionalhead loss, and the shear stress on the pipe wall. What power of pump will be requiredto maintain the flow? Use a Moody chart.
As part of a drainage improvement project, a drainage ditch will be straightened and cleaned. As a result, the lenght of the ditch will decrease from 1800 ft to 1400 ft and the mannings roughness factor will be reduced to 0.018 from 0.022.
Annual rainfall over the watershed is 36 inches and the annual runoff from the catchment is 12 inches. Evaporation from the reservoir averages 40 inches per year. The municipal water demand equals 100 million gallons per day
the steel g 12000 ksi pipe shown in the adjoining figure is fixed to the wall support at c.nbspthe bolt holes in the
The variation in the diffusion coefficient with temperature, over an appropriate range of temperature, can usually be approximated as follows: D= (D0)e^-(Q/(KT) where, Q = activation energy (eV/atom) and k = Boltzmann's constant (8.616*10-5 eV/ato..
consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam.nbspassume length l
Thirty six year old Johnson was in his last semester of his graduate program in Civil engineering. Father of two small children, he was anxious to get his degree so that he could spend more time with his family.
Discuss bracing types of buildings with real-life example. Provide photograph or sketch for each type of bracing.
a) determine by direct integration the polar moment of inertia of the semiannular area shown with respect to point O b) Using the result of part a, determine the moments of inertia of the given area with respect to the x and y axes
Compute the geodetic coordinates of the station QBN from station MDU If coordinates of station MDU are f = 39°51'55"N, ? = 104°40'58"W Distance = 30km, Az = 243°40'48”, h = 1850m, dh= -20. Ellipsoid GRS80
A 250 cubic meter reaction tank contains a waste water having an ultimate BOD concentration of 755 mg/L. If the BOD reaction rate constant is -0.352/day, how much BOD is remaining after 12.0 days
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.
Estimate the value of the coefficient of at-rest earth pressure forthe deposit. If, when the water table was at the ground surface, the deposit was normallyconsolidated,would it still be normally consolidated with the water tablelowered? A reason mus..
