What does that mean?
PBRI 5.1, #6:
What is an example of a nonlinear mechanical effect?
a) Air resistance caused by localized eddies in the evacuated jar
b) Thermal expansion of the fulcrum due to friction
c) Induced electrical current in the moving bob
d) Deformation of the cable caused by centripetal acceleration
Answer is D, but I am unfamiliar with the terms "nonlinear mechanical effect" and "eddies".
