I see. I guess my specific question is, if the bar as shown in number 7 is placed as is, should i take into account the weight? Like a suspended mass with spring, the weight is not considered. Is the same applies for this particular problem?Dr.D said:
I got those in mind but if I choose sum of the moment method at pivot A, it gives mg(L/2) - k(delta)(L) - k(y)(L) = I(alpha). Does that mean mg(L/2) is equal to k(delta)(L)?Dr.D said:
A dynamic vibration problem is a phenomenon in which an object or structure experiences vibrations or oscillations due to external forces or disturbances. These vibrations can be harmful and affect the performance or stability of the object.
The main causes of dynamic vibration problems include unbalanced forces, resonance, and external disturbances such as wind or earthquakes. These forces can cause the object to vibrate at its natural frequency, leading to potential damage.
Dynamic vibration problems can be prevented by using proper design and engineering techniques. This may include using materials with high damping properties, implementing vibration isolation methods, and avoiding resonance conditions.
Ignoring dynamic vibration problems can result in structural damage, reduced performance, and even safety hazards. The vibrations can also cause fatigue and wear on the object, leading to costly repairs or replacements.
To solve dynamic vibration problems, it is important to first identify the root cause. This may involve conducting vibration analysis and using tools such as finite element analysis. Once the cause is determined, appropriate measures can be taken to mitigate or eliminate the vibrations.
