Calculate the forces in members CB, CG, and FG for the loaded truss without first calculating the force in any other member.
The bar is prevented from rotating by the two pegsA and B fixed to the plate. Determine the acceleration a of the plate for which no force is exerted on the bar by either peg A or B.
Determine the number of gallons of paint needed to paint the outside surface of the water-supply tank, which consists of a hemispherical bottom, cylindrical sides, and a conical top. Each gallon of paint can cover 250 ft^2
plot the exit pressure, the exit velocity, and the mass flow rate through the nozzle versus the back pressure Pb for 6.0 ≥ Pb c ≥ 3.0MPa. Treat the steam as an ideal gas with k =1.3, cp= 1.872 kJ/kg · K, and R =0.462 kJ/kg · K.
The air above the liquid is under a pressure of 5 psig, and the specific gravity of the liquid in the tank is 0.80. If the rectangular gate is 6 ft wide and if y1 = 1 ft and y2 = 10 ft, what force P is required to hold the gate in place
$25,000 is deposited in a savings account that pays 10% interest, compounded monthly. Equal annual withdrawls are to be made from the account, beginning one year from now and countinuing forever.
You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
The evaluation of various possible scenarios (either future or past) using simulation models can be tremendously valuable as a tool used in strategic plan development.
an overpass is being built over the pvi of an existing equal tangent sag curve. the sag curve has a 70 mih design speed
The brass tube AB (E=105 GPa) has a cross-sectional area of 140 mm^2 and is fitted with a plug at A. The tube is attached at B to a rigid plate that is itself attached at C to the bottom of an aluminum cylinder
A vertical tank of 4.sm2 cross-sectional area is filled with 13.5m3 of water, 9.0m3 0f a fluid with an s.G. of 3.2,6.75;. or oir with an s.G. of 0.85 and 0.9m3 of mercury with an s.G. of 13.s7.
A concrete mix with a 3in slump, w/c ratio of .5, and sand with a fineness modulus of 2.4 contains 1700lb/yd3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard
An adiabatic piston-cylinder device equipped with a spring maintains the pressure inside at at 300kPa when the volume is 0, and 3000kPa when the volume is 5 m3. The device is connected to a steam line maintained at 1500kPa and 200 C, and the initial ..
