60NiTi Summary Remarks and Enabling Benefits • 60NiTi can substitute for 440C steel in spherical bearings: – Friction and wear properties meet SAE requirements. – 60NiTi is not adversely affected by common aircraft contaminants (deicing and hydraulic fluids). • Reduced weight propulsion and control systems: – Lighter weight materials: NiTi alloys weigh 15% less than steel.

Magic Spheres (Science of Density) – SICK Science. A heavy, metal ball bearing "magically" transforms into a Ping-Pong® ball in a jar of un-popped popcorn. Science is not magic but magic definitely needs science. Say this to your friends, "Let's make this metal ball bearing become a featherweight plastic sphere.".

In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space.However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or ...

The density of steel usually ranges between 7.75 and 8.05 g/cm3 and the density of mercury is 13.534 g/cm3. Mercury is denser than steel this will mean that the buoyant force is large enough to float the steel ball. Different materials usually have different densities, so density is an important concept regarding buoyancy, purity and packaging.
