Ah, when you see that "a = -ω²x" shape, chala simple: check if the acceleration is against the displacement and if that omega is constant, na? But in my shop, with the old ceiling fan's wobble, the equation fits perfectly but the motion still fails—a worn bearing adds its own *tamasha*. Sometimes the maths says 'simple harmonic' but the machine, bless it, has other plans.
