“…Critical damping is an important aspect of oscillation in engineering, physics, and other fields. [11] highlighted the use of critical damping in shock absorbers to bring them back smoothly to their original position without any overshoot, which could cause instability. [12] added that critical damping is used in machinery to prevent oscillations and vibrations, which can cause damage to the machinery and affect its performance.…”

The Simple Harmonic Oscillation (SHO) is a fundamental concept in physics, as it describes a large variety of phenomena that occur in nature, such as the motion of pendulums, mass-spring systems, and atoms. A thorough understanding of SHO can provide a good foundation for learning more advanced topics in physics, making it an essential topic for students to learn. Computer simulation technology provides an effective way to model SHO phenomena in the classroom. This technology allows students to explore SHO concepts visually and to replicate experiments that would be cumbersome or impossible to conduct otherwise. However, there are few compilations of SHO simulations appropriate for classroom use. This paper presented a compilation of SHO experiments that utilize computer simulation of PhET. The compiled experiments cover a broad range of SHO concepts, including proving the relationship of energy and amplitude, velocity and displacement, acceleration and displacement and types of damping. These experiments are suitable for classrooms of all levels and can be used to broaden and enrich students' understanding of SHO. Overall, the simulation-based experiments presented here offer a valuable resource for educators seeking to improve their students' understanding of SHO.

In the present investigation, with the aim of performance improvement of size-dependent bi-gyroscopic structures, the vibrational behavior of spinning small-scale tunes conveying fluid embedded in various foundations subjected to distributed tangential load and hygro-thermo-magnetic environments by including gravitational effect is investigated. The modified couple stress theory is used to study the microscale tube, and the modified nonlocal theory is utilized to model the nanoscale tubes. A parametric investigation is also conducted to highlight the impacts of various key factors such as gravity, flow profile modification factor, fluid velocity, spinning speed, substrate coefficients, boundary conditions, size-dependent parameters, and environmental attacks on divergence and flutter thresholds of the structure. The dynamical equations are solved using Laplace transformation as well as Galerkin discretization techniques, and forward and backward frequencies are identified accordingly. Meanwhile, the instability borders of the system are obtained analytically. Campbell and stability diagrams, and the time history of the system, are acquired. The results revealed that contrary to influences of gravity, magnetization, and size-dependent parameters, the compressive tangential load and humidity have decreasing effects on the vibrational frequencies and make the system prone to experience static and dynamical instabilities. Moreover, it is determined that applying the viscous foundation eliminates the re-stabilization zone in the system stability evolution, and after the occurrence of the divergence phenomenon, the system immediately undergoes the flutter instability.
