Hemisphere centroid
Web30 dec. 2013 · The area of a surface generated by rotating a curve about an axis (of rotation), which does not pass through the curve, is the length of the curve times the distance traveled by the centroid of the curve. The distance from the centroid to the x-axis is the radius of rotation and is \(r = y = 0.3663678347991 \). The centroid of a uniformly dense planar lamina, such as in figure (a) below, may be determined experimentally by using a plumbline and a pin to find the collocated center of mass of a thin body of uniform density having the same shape. The body is held by the pin, inserted at a point, off the presumed centroid in such a way that it can freely rotate around the pin; the plumb line i…

Figure 1 EMG 251- M U −2024 Question 2 Determine the location yˉ of the centroid C of the beam's cross-sectional area. Then compute the moment of inertia for the area about the axis x in figure 2 .
WebThe centroid is the bottommost point (it's the projection of the centre of mass onto the spherical surface). This should work aside from a few ambiguous cases e.g. a strip going around the equator, where I can just pick a sensible point. Happy to discuss in a new question if you think it's worth it. – Jason Davies Dec 7, 2012 at 23:27
