A note on Vibration and Washing Machines
If you have taken a sneak peak into a washing machine then you might have noticed that it has a concrete block inside (also why they are heavy).
Their primary purpose is to absorb vibrations caused by the rotating body (in this case the drum) and keep the machine stable.
But this begs the question of what would happen if it didn’t have the concrete dampener. The above gif from the secret life of machines shows you exactly that.
With no cushion to dampen out the vibration, the machine propels forward from the unbalanced linear and torsional forces and eventually breaks down.
Have a great day!
