However, the effective length of fiber that both light fields travel through are completely unpredictable.
The effective length of the platform was once only enough to accommodate three 18 m train cars.
The effective length of the sample being measured is the distance between the two inner electrodes.
They then began to measure the effective length (and therefore range) of the weapon in calibers.
The effective length of the limb, as the draw commences, is therefore shorter.
Generally the thicker the string, the shorter the effective length.
This changes the effective length of the pendulum, and hence, the period.
To accelerate the processing the accumulator works with an effective length.
Moving the regulator slides the slit up or down the spring, changing its effective length.
A line can be programmed to vary in effective length.
