Problem 1: Compute the plastic moment for strong axis bending, Mpx, of the Tee section shown below.
a)
b) use the same cross section as in a), but assume A36 steel (Fy = 36 ksi) for the flange plate and A514 Gr. 100 (Fy = 100 Ksi) for the stem.
Problem 2: A simply welded I-section beam carries a concentrated load W at midspan. The load is 20% dead load and 80% live load. Determine the maximum service load W that can be permitted to be carried. Use A36 (Fy = 36Ksi) steel, and assume that the beam is a compact section and laterally supported. Include the selfweight of the beam in your calculations. Deflection is not of concern.
Problem 3: Select the lightest W section to carry a uniformly distributed dead load of 2 k/ft in addition to the beam weight, and uniformity distributed live load of 18 k/ft. the beam is simply supported over a span of 7f. Use A992 (Fy = 50 Ksi) steel, and assume that the beam is laterally supported. Deflection is not of concern.
Determine appropriate dimensions of the finished water clearwells to achieve adequate disinfection using chlorine. Flow Rate Q = 30 million gallons paer day.
given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
An electron is released from rest at a perpendicular distance of 9.9 cm from a line of charge on a very long nonconducting rod. That charge is uniformly distributed, with 9.0 ?C per meter. What is the magnitude of the electron's initial accelerati..
A Proctor compaction test in the laboratory on a borrow pit soil gives a maximum dry unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air What type of heat transfer mechanism is employed in thi..
A four-wheel tractor whose operating weight is 47,877 lb is pulled up a road whose slope is +3.5% at a uniform speed. If the average tension in the towing cable is 4,860lb, what is the rolling resistance of the road
An insulated piston cylinder device initially contains 0.01m^3 of steam at 473 K the force on the piston is such that it maintains a constant pressure of 400kpa Inside . A valve is now opened and steam at 1Mpa at 473 K is allowed to enter the cylinde..
an electric motor is rated at 10 horsepower hp and costs 800. its full load efficiency is specified to be 85. a newly
Two control points A "station" (1000E, 1000N) and B "backsight" (594.22E, 877.68N) are available within the area. Indicate the procedure to satisfy the orientation and calculate the required total station reading towards B.
The x-component of a velocity field is ax+b.If the flow is steady, two-dimentional and incompressible; generate an expression for velocity component in the y-direction as a function of x and y.
If a torque of T = 1,100 N-m is applied to the composite assembly, determine: (a) the maximum shear stress in the aluminum tube and in the steel core. (b) the rotation angle of end B relative to end A.
a 25-mm diameter steel cylinder 300-mm long falls, because of its own weight, at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. A castor-oil film of constant thickness is between the cylinder and the tube.
