Problem 1. For the truss structure shown below, determine
a. The reaction forces at D and F
b. The force in each truss member. Indicate whether each is in tension or compression.
Problem 2. Determine for both the x and y axis:a. Centroid x¯ and y¯b. Area moment of inertia Ix and Iyc. Verify results in AutoCAD. Draw shape and region. Then use massprop. Show printout of drawing and AutoCAD text window.
Problem 3. Determine how much force is needed P [#] in order to keep the block in static equilibrium with an angle θ = 33°.
Vision Technologies Inc., is a small company that uses ultra-wideband technology to develop devices that can detect objects (including people) inside of buildings, behind walls, or below ground.
A satellite would have a mass of 200 kg on the surface of the moon. Determine the weight of the satellite in pounds when it is in orbit 10,000 mi. above the surface of the earth.
Double the width of the window, using widen, set the height of the window so that it is the same as the width, and set the title to the new value "Square Window".
Another way to treat acid mine drainage is to add limestone at the beginning of a narrow AMD stream to precipitate the metals. The first order rate constant is 10/day. Assume the stream is 3ft wide and 1ft deep
Carbon dioxide at 30 C and 320 kPa absolute pressure expands isothermally to an absolute pressure of 170 kPa. Determine the final density of the gas.
an existing water treatment plant is producing an average flow of 0.5 mgd. due to several limitations the plant only
Gaseous oxygen (99% pure, molar basis) is to be produced at a rate of 350ft^3/hr in a Linde single column plant. The column operates at a pressure of 1 atm. Air leaves the compressor at a pressure of 10 atm.
A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe, what will be the discharge?
Estimate the theoretical fracture strength of a brittle material ifit is known that fracture occurs by the propagation of anelliptically shaped surface crack of length 0.2 mm(0.007874 in)
Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.
what policies were implemented during and after WW1,WW2,Cold war?
A pump of 80% efficiency lifts water from one large open tank to another; the difference in water surface elevations is 20 feet. The pipe is relatively smooth (f = 0.0122), and has 3 elbows, each with a loss coefficient of 2/3.
