A bias of mass of the screen toward one side. If one side of a screen has a greater mass than the other, the two sides will vibrate with different acceleration and amplitude (throw). A difference in the mass of screen box components from one side to the other or a bias of mass of feed material to one side will result in uneven motion.

A simpler approach would be to note that the intensity is proportional to the square of the amplitude, and since changing the position of the second source increases the amplitude from (4.46cm) to (16cm) (double the individual wave amplitude), which is an increase of a factor of 3.59, the intensity increases by a factor of (3.59^2=12.9 ...

Observe that whenever the amplitude increased by a given factor, the energy value is increased by the same factor squared. For example, changing the amplitude from 1 unit to 2 units represents a 2-fold increase in the amplitude and is accompanied by a 4-fold (2 2) increase in the energy; thus 2 units of energy becomes 4 times bigger - 8 units.
