# Vibration isolation
# Scope: Viscously damped SDOF displacement transmissibility at one frequency ratio.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

ratio = 3
damping = 0.1

transmissibility := sqrt((1+(2*damping*ratio)^2)/((1-ratio^2)^2+(2*damping*ratio)^2))

check transmissibility target: transmissibility <= 0.2

scenario alternative: ratio = 2.4
