Explain how the window washer lifts his platform using the
pulley system. Refer to the diagram to describe what
happens when the force is exerted. Does the pulley system
increase or decrease the input force needed? As a result of
using the pulley, what happens to the direction of the force?
Click on screen to continue
The pulley system increases the distance over
which the force is exerted, decreases the input
force needed, and changes the direction of the
force. To pull himself toward the top of the
building, the window washer pulls down on a
rope. The distance the window washer must pull
the rope (the input distance) is much greater than
the distance he moves (the output distance). When
the input distance of a machine is larger than the
output distance, the output force is larger than the
input force.
