Consider for example the function (,) = (+,) which maps every point of the open unit disk to another point on the open unit disk to the right of the given one. But for the closed unit disk it fixes every point on the half circle x 2 + y 2 = 1 , x > 0. {\displaystyle x^{2}+y^{2}=1,x>0.} See more In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle. A disk is said to be closed if it contains the circle that constitutes its boundary, and open if it does not. For a radius, See more The disk has circular symmetry. The open disk and the closed disk are not topologically equivalent (that is, they are not homeomorphic), as they have different topological properties from each other. For instance, every closed disk is compact whereas every … See more • Unit disk, a disk with radius one • Annulus (mathematics), the region between two concentric circles See more In Cartesian coordinates, the open disk of center $${\displaystyle (a,b)}$$ and radius R is given by the formula $${\displaystyle D=\{(x,y)\in {\mathbb {R} ^{2}}:(x-a)^{2}+(y-b)^{2} plastic forks to deter squirrelsWebThe moment of inertia of a solid disk about this axis is given in Figure 10.20 to be 1 2 M R 2.
