So, corresponding sides and corresponding angles of congruent figures have the same measures. The measures of corresponding angles in similar figures are the same, but the measures of corresponding sides in similar figures are multiples of each other (i.e. they are proportional).
An industrial flywheel. A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. Energy is transferred to a flywheel by the application of a torque to it, thereby increasing its rotational speed, and hence its stored energy. Conversely, a flywheel releases stored energy by applying torque to a mechanical load, thereby decreasing the flywheel's rotational speed.
These are the common parts found on a traditional spinning wheel. The arrangement of these parts may vary from wheel to wheel. A. Fly Wheel â The wheel that rotates when treadling and causes the other various parts to operate. B. Drive Band â A cord that goes around the fly wheel and the flyer whorl. C. Flyer â A U-shaped piece of wood with hooks lined up on one or both arms. The hooks are used to store the yarn evenly on the bobbin.
