The spin dry cycle in a washing machine is 660 RPM's or Rev/ Min. How many revolution per second is this?
What is the Time(T) for one revolution?
If the tub's radius is.4 meters, what is the rim's speed?
Now then, what is it's centrifugal acceleration?
Roughly how many times larger than Earth's acceleration(10 m/sec^2) is this? How many G's?
Someone please awnser this question!
