Consider the construction shown in (Figure 1). The mass of each ball is m. Ignore the mass of the rods to which the balls are attached. Determine the rotational inertia of the construction about an axis perpendicular to the picture and passing through point A.

Express your answer in terms of m and l.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
