Bridge destroyed by harmonic motion

WebThe resulting equation is similar to the force equation for the damped harmonic oscillator, with the addition of the driving force: −kx−bdx dt +F 0sin(ωt) =md2x dt2. − k x − b d x d t + F 0 sin ( ω t) = m d 2 x d t 2. When an oscillator is forced with a periodic driving force, the motion may seem chaotic. WebNov 5, 2024 · Driven harmonic oscillators are damped oscillators further affected by an externally applied force F (t). Newton’s second law takes the form F ( t) − k x − c d x d t = m d 2 x d t 2. It is usually rewritten into the form d 2 x d t 2 + 2 ζ ω 0 d x d t + ω 0 2 x = F ( t) m. This equation can be solved exactly for any driving force, using ...

The total energy is the sum of the kinetic and elastic potential energy of a simple harmonic oscillator: E=K+U_s E = K +U s. The total energy of the oscillator is constant in the absence of friction. When one type of energy decreases, the other increases to maintain the same total energy. Figure 3.
