A steel circular hollow cylinder is supported on a circular steel plate.This arrangement is supported on a concrete pedestal. The column has outside diameter d = 250 mm and supports a axial load P = 750 kN.
(a) If the allowable stress in the cylinder is 55 MPa, what is the maximum internal diameter (nearest integer, such as 10, 11, 12, ...., in units of millimetres) of the cylinder?
(b) If the bearing stress on the concrete pedestal must not exceed 11.5 MPa, what is the minimum required diameter D of the base plate? You can assume the cylinder is loaded up to Pallow (not 750 kN) with the internal diameter calculated in part (a).Hint: The new allowable load Pallow will be slightly larger than 750 kN.
A belt is wrapped around a pulley for 180 degrees. The loose-side belt tension is 100 lb and the coefficient of static friction is 0.30. Calculate the maximum belt tension if motion is impending.
what is the effect of temperature on compressive strength of concrete?
Benefits associated with a project are $10,000 forever starting in year 1. The costs are $20,000 in year 0 and $20,000 in year 3. What is the B/C ratio at i=12% per year. First determine present worth for benefit and cost, respectively.
Collars A and B are connected by a 25 in long wire and can slide freely on frictionless rods. If a 60 lb force Q is applied to B. determine tension in wire when (black) x = 9 in and b) corresponding mag of force P required to maintain equilibrium ..
If the peak-hour factor is .90 and all of the drivers are regular users, what is the level of the service of this compound-grade freeway segment?
Compute the 50 year flood discharge on a large creek in Northern Ohio if the total discharge area is 75 mi^2. The average soil infiltration is 0.5 in./hr; the main channel slope is 0.008.
a brass wire of diameter d=1/6 in is stretched between rigid supports with an initial tension T of 37lb. assume the coefficient of thermal expansion is 10.6X10^-6 / F and the modulus of elasticity is 15X10^6 psi.
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
A jar test has shown that the optimum dose of ferric chlorideconsumes all of the alkalinity. If the amount of the ferricchloride that is in excess is 10 mg/l, how much lime(Ca(OH)2) in mg/l must be added to neutralize the acidformed.
A water pipeline system is made up of three links in parallel. In any given year, on average, 99 in 100 pumps do not fail. The conditions in the links are statistically independent of each other.
For almost all new coal plants, Clean Air Act emission standards limit emissions of sulfur dioxide (SO2) to 260 grams per million kJ of heat input (fuel value). They also restrict particulate emissions to 13 g/106 kJ.
Estimate the daily emissions of sulfur dioxide, nitrogen oxides as NO2, and particulate matter from an industrial steam-generating plant equipped with a dry-bottom pulvurized-coal firing system.
