Picture by: Drew

This picture is an arrangement of fixed and moving parts for doing work, each part having some special job to do.  Some push and some pull.  The wheels on the motorcycle push the machine forward.

The pulley on the crane pulls the big ball up in the air.  The blades on the helicopter push the air around.   The jet's engine pushes the jet forward.  The worker has to pull the door open to go in the "porta potty."  After all this pushing and pulling the worker is happy to go home, pull his shoes off, push up the foot of his recliner, and go to sleep. ZZZZZZZZZZZZZZZZZZZZZZZ
