Drilled Physics Ball Set – Arbor Scientific

These 1" (25mm) drilled physics balls are great for doing Newtonian physics experiments such as collisions or for use in mass/volume experiments. A 3mm hole has been exactly drilled in the center of each sphere in such a way as to allow for the recessing of a knot. This allows the set to also be used as pendulums.

ball bearing | mechanics | Britannica

ball bearing, one of the two members of the class of rolling, or so-called antifriction, bearings (the other member of the class is the roller bearing).The function of a ball bearing is to connect two machine members that move relative to one another in such a manner that the frictional resistance to motion is minimal. In many applications one of the members is a rotating shaft …

How to Calculate Thermal Expansion of Steel - Sciencing

Multiply the product of the expansion coefficient and the temperature increase by the original length of the steel. Finishing this example, if the steel rod was originally 100 inches long, you would multiply 100 by 0.000036 to find that the steel would be 0.0036 inches longer when subjected to heat.
