Physics
A conducting pendulum loses mechanical energy to induced current. Compare solid and slotted plates using a lumped-loop electromagnetic model with an explicit heat budget.
Release both plates together. Compare motion and heat; slots weaken the braking.
Equations Φ(x) = B A exp(−x²/(2w²)) ε = −(dΦ/dx) x′; I = ε/R; F = I dΦ/dx Pheat = I² R; d(Emechanical + Q)/dt = 0
Physics
The averaged Garcia–Hubbard model shows energy exchange between spin, pitch and roll. Change skew and spin direction to observe asymmetric reversal times.
Physics
Wind couples bending and torsion in an illustrative bridge-section model. Compare subcritical decay with flutter above the calculated linear threshold and nonlinear amplitude limitation.
