Answer Posted / Dahrmendra Kumar
Excessive vibration in a machinery may not always be immediately noticeable, as it can occur at frequencies beyond human perception. However, it can still lead to mechanical failures over time. Vibration is transmitted between elastic materials or components through the same mechanical interaction process mentioned earlier. When a machine experiences excessive vibration, it can cause premature wear and tear on moving parts, potentially leading to failure.
