On all pneumatic player pianos, the paper is pulled on to a take-up spool, and as more paper winds on, so the effective diameter of the spool increases, and with it the paper speed.
32.
This was necessary because the supply reel is always decreasing in effective diameter while the take up reel is increasing in effective diameter as the tape moves from one reel to the other during encoding, and again when backspacing or rewinding.

Trains and trams can turn corners without wheel-slip because the outer horizontal part of the wheels has a slightly rail in different ( horizontal ) places so that the outer wheel has a larger effective diameter than the inner wheel.

By having the chainring at its peak effective diameter with the cranks level, where the rider has maximum leverage over the crank during the power stroke, these designs are supposed to make better use of the rider's power output.
36.
Without proper fusion to the base materials provided by sufficient arc time on the weld, a project inspector cannot ensure the effective diameter of the puddle weld therefore he or she cannot guarantee the published load capacities unless they witness the actual installation.

Through the technique of very-long-baseline interferometry ( VLBI ), many independent radio antennae separated by hundreds or thousands of miles can be used in concert to create a " virtual " telescope with an effective diameter of the entire planet.

As the warp beam empties its effective diameter changes making the warp slacker-tension is maintained by adding a wooden pulley to the beam, around which are two turns of rope that are attached to mill weights-thus retarding the beam through friction.

While the nail or screw will turn around in a full circle ( and more ) the railroad wheelset behaves differently because as soon at it starts to turn in a curve, the effective diameters change in such a way as to decrease the curvature of the path.
40.
But the trajectory has a slope at this point ( it is a straight line which crosses diagonally over the centerline of the track ) so that it overshoots the centerline of the track and the effective diameters reverse ( the formerly smaller diameter wheel becomes the larger diameter and conversely ).
