4.1.2 The Voltage State<br />
AS-Chap. 4 - 16<br />
• mechanical analogue: 2 pendula with mass M and length l coupled via twistable bar<br />
- for negligible screening (¯L ¿ 1): rigid bar<br />
relative angle 1 - 2 = 2¼© ext /© 0 fixed by external flux<br />
single combined pendulum with mass 2M, distance from pivot point: l cos(( 1 - 2 )/2)<br />
without torque: pendula reside at ( 1 - 2 )/2<br />
with torque (bias current): combined pendula rotate<br />
