Write a program that will calculate the location of the centroid of a semicircle (measured from the diameter line). This may be accomplished by dividing the area into slices of uniform width, either parallel or perpendicular to the diameter, and applying Equation (7.4). User input is to be the radius and width of the slice. Check the result with that obtained from Table 2. Note how the accuracy varies with the choice of the slice width.Equation (7.4)
a 2 lb brick slides off of a roof with a slope of tan-134. that is about when the brick leaves the roof it is 30 ft off
at steady state work at a rate of 5 kw is done by a paddle wheel on a slurry contained within a closed rigid tank. heat
Steam flows through a turbine. The inlet stream is at 1200 KPa and 290 C. The pressure at the exit is 75 KPa. A) Determine the quality and temperature of the steam at the exit. B) Determine the specific work produced by the turbine.
the composite beam is made of a-36 steel a bonded to c83400 red brass b and has the cross section shown. if it is
Show that the ?ow represented by c ¼ 10 lnðx2 þ y2Þ m2=s is an incompressible ?ow. Also, (a) Find the velocity potential f.
Two objects are connected by a light string that passes over a frictionless pulley as shown in fig. Assume the incline is frictionless and take m1 = 2.00 kg, m2 = 6.00 kg, and 0 = 55.0o. Find the magnitude of the acceleration of the objects
two kilograms of air within a piston-cylinder assembly executes a carnot power cycle with maximum and minimum
A welding heat source is capable of transferring 150 Btu/min to the surface of a metal part.
Why is that in FEA it is preferred to analyze thin structures using shell elements rather than the solid elements?
After machining, the length was found to be 10.004 in. What was the average residual stress in the layer that was machined away? For the brass, E = 110 GPa. For simplicity, neglect the Poisson effects.
consider a concentric circular-tube annulus with outer diameter 2.5cm and inner diameter 1.25cm in which air is flowing
The rotational partition function for a sample of carbonyl sulide (OCS) is found to be 25.0. Above roughly what J value do we expect to see the population (the number of molecules per J level) rapidly decreasing?
