If a thermal mass at a certain temperature is surrounded by any fluid with another temperature, we will observe a temperature change of both. If system boundaries are in place and the system is considered adiabatic, a new overall temperature will be reached for the whole system.
This tutorial deals with the dynamic behavior of a mass/spring system in free conditions.
Systems with one Degree of Freedom (DoF) make possible to introduce the first important phenomenon occurring in mechanical vibratory systems: natural pulsation, eigen frequency, damping… It helps to understand the behavior of more complex systems with additional DoF.
This tutorial deals with the dynamic behavior of a mass/spring system in forced conditions.
Once the free response of the system is understood (refer to the course Mechanics and vibrations - Free response of a system with one Degree of Freedom), we can characterize the behavior of the system with a sinusoidal excitation. That is the purpose of this course.
If we throw a mass with an initial vertical velocity, the maximum height that will be reached by the mass is not affected by the weight of the mass. The motion of the mass can be described just taking into account the initial velocity, the gravity acceleration and the time.
