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} Web6.2.1 Determine the volume of a solid by integrating a cross-section (the slicing method). 6.2.2 Find the volume of a solid of revolution using the disk method. 6.2.3 Find the volume of a solid of revolution with a cavity using the washer method.

Webgiven that the formula for the angular acceleration is: alpha = torque/mr^2. Under the assumption that the force is applied in a 90 degree angle it can be simplified to: F*r/mr^2 which leads to: alpha = F/mr. WebWe use Equation 11.12 to find the precessional angular velocity of the gyroscope. This allows us to find the period of precession. Solution The moment of inertia of the disk is I = 1 2 m r 2 = 1 2 ( 0.30 kg) ( 0.05 m) 2 = 3.75 × 10 −4 kg · m 2. The angular velocity of the disk is 20.0 rev / s = 20.0 ( 2 π) rad / s = 125.66 rad / s. palodent plus sectional matrix
