An HSS 10×6×5?16 with Fy = 46 ksi is used as a column. The length is 16 feet. Both ends are pinned, and there is support against weak axis buckling at a point 6 feet from the top. Determine the design strength for LRFD.
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.
calculate the cracking moment (resisting moment) for an unreinforcedconcrete beam that is 10 in. wide, 16 in. high. assume normal weight concrete with 3000 psi = f prime sub c. use the internal couple method and check with the flexure formula.
Write a computer program that can be used to determine the internal shear and moment at any specified location x along the beam, and plot the shear and moment diagrams for the beam.
The plant currently has one CMFR for removal of chromium. How many more identical reactors does the sony music company require to meet the regulatory requirements for chromium discharge of 0.01 mg/L into the Pitman Sewer?
A hollow circular shaft is loaded in pure torsion. Describe how the shear stress due to the applied torque varies on a cross section whose unit normal vector lies parallel to the long axis of the shaft.
The member is 24ft long with pinned end supports and is laterally supported in the weak direction at the one-third points of the total column length. Use 50 ksi steel.
Aluminum ion (Al3+) is present in an industrial wastewater at 3 mg/L. The treatment facility wants to precipitate out the aluminum until there is only 0.2 mg/L remaining. What pH is required to acheive this aluminum ion concentration
The centres of the piers in a bridge are 8.0m apart. The piers are each 0.8m wide. Water flow under the bridge with an upstream depth and velocity of 4.0m and 4.0m/s respectively. The pier has a drag coefficient Cd = 1.5.
Select the number and size of reinforcing bars required to resist a total factored moment of 180 ft. kips for a rectangular section with b = 12 in., d = 19.5 in., h = 24 in., f'c = 4 ksi, and fy = 60 ksi.
A surveyor is going to take a 5.5 mile sight across a lake from the top of one tower to a target on the top of another tower. It is desired to keep the line of sight 6 ft above the lake surface.
The atmosphere is stable with a lapse rate of -0.2C/100m. The surface air temperature is 15C. A parcel of air is released at the ground with a temperature of 25C. Calculate the maximum mixing height in meters.
The moist unit weights and degrees of saturation of a soil are given: moist unit weight (1) = 16.62 kN/m^3, degree of saturation (1) = 50%; moist unit weight (2) = 17.71 kN/m^3, degree of saturation (2) = 75%.
