MA=120/10
effort= 72/MA
distance= 6m*MA
max lift= 200*MA
A bucket of weight 72 N is lifted from a well by the wheel and axle system shown below:
If the diameter of the circle of the crank handle (diameter of the wheel) is 120 cm and the diameter of the shaft that the rope is wrapped around (diameter of the axle) is 10 cm,
What is the mechanical advantage of this machine?
What effort would be required to lift the bucket out of the well?
Over what distance would the handle of the crank have to be turned in order for the bucket to be lifted 6 m out of the well?
If an effort of 200 N is the largest that could be exerted in turning the handle, what would be the largest weight that could be lifted out of the well?
