Solid of revolution - Wikipedia, the free encyclopedia In mathematics, engineering, and manufacturing, a solid of revolution is a solid figure obtained by rotating a plane figure around some straight line (the axis) that lies on the same plane. Assuming that the figure lies entirely on one side of the axis, the solid's volume is equal to the length of the circle described by the figure's barycenter, times the figure's area. A representative disk is three-dimensional volume element of a solid of revolution. en.wikipedia.org /wiki/Solid_of_revolution   (621 words)

The Washer Method for Solids of Revolution   (Site not responding. Last check: 2007-11-05) If we slice the solid perpendicular to the axis of revolution as in Figure 2, the resulting solid resembles a washer, hence the technique for calculating the volume of the solid of revolution is called the washer method. Note that the washer is sliced perpendicular to the hole (axis of revolution) while the orientation of the shell is parallel to the hole (axis of revolution). For a solid of revolution generated by revolving a region about the y-axis, the inner and outer radii are functions of y. mathdemos.gcsu.edu /washermethod   (1280 words)

Visualizations for Volumes of Solids in Calculus   (Site not responding. Last check: 2007-11-05) Rather than introduce volumes of solids of revolution by a purely formula-driven approach, these demos provide the opportunity for visualization of the basic approximating elements that lead to the standard calculus expressions that, when computed, give the desired volumes. We tell students that we can cut the solid into pieces that have a known cross section or, in the case of solids of revolution, we dissect the surface of revolution into "disks", "washers," or "cylindrical shells". Solids of Revolution: The Method of Shells involves revolving a region bounded by a curve y = f(x) and the domain interval [a,b] about the y-axis. mathdemos.gcsu.edu /solids   (972 words)

Vision system for analyzing solid-of-revolution radius profile - Patent 5918196 The resulting parts are referred to as "solids of revolution." Examples include a clay pot produced on a rotating wheel, a baseball bat shaped on a lathe, or a silicon crystal grown from a rotating seed dipped into a silicon melt. A common non-contact approach for gauging parts described as solids of revolution involves viewing the object with a camera whose line-of-sight is normal to the object's axis of revolution. Repeating such measurements at many locations along the full length of the solid of revolution, one generally obtains a radius profile as in the case of the general radial profile inspection system, or a time-varying radius and melt level of a semiconductor crystal, as in the specialized case of a crystal growth inspection system. www.freepatentsonline.com /5918196.html   (6104 words)

Sandia Joins Revolution In Solid-State Lighting   (Site not responding. Last check: 2007-11-05) Sandia National Laboratories is among the research entities around the country at the forefront of the revolution. In some applications they also enable significant cost savings due to their lower consumption of energy: LED-based red traffic lights, for example, consume one-tenth the energy of their incandescent counterparts, enabling them to pay for themselves in as little as one year. Researchers believe that the development and adoption of solid state lighting technology could reduce the nation's electrical consumption by 10 percent. www.pinian.com /revolution_in_solid_state_lighting.html   (635 words)

SparkNotes: Applications of the Integral: Volumes of Solids The application of integrals to the computation of areas in the plane can be extended to the computation of certain volumes in space, namely those of solids of revolution. The shell method is applied to a solid obtained by revolving the region below the graph of a function f (x) from a to b about the y-axis. Even when the cross-section is not a disk (as it is in the case of more general solids of revolution), there may still be a function A(x) that gives the area of the cross section obtained by slicing the solid with the plane through x and perpendicular to the x-axis. sparknotes.com /math/calcbc2/applicationsoftheintegral/section2.rhtml   (618 words)

Last check: 2007-11-05) Date: 05/21/2001 at 09:32:13 From: Stan Winston Subject: Alternate Surface Area of Solid of Revolution Formula My teacher mentioned that we were going to be looking at surface areas of solids of revolution shortly after we did volumes of rotation. When the multiple circumferences are accumulated by integration, it's the same as adding the areas of multiple cylindrical strips with infinitely small widths, which should give me the surface area. In fact, the only solid that I've found my formula to work for is the cylinder. mathforum.org /library/drmath/view/51814.html   (828 words)
