What is effort (input) force?
the force one exerts on a machine
the force which an effort force must overcome in order to do work on an object via a simple machine.
the force the machine exerts on a object
the output work times the input distance
What is resistance (output) force?
the force required by a machine in order to accomplish work (the force you put on the machine)
The force that is exerted by a machine
the force the machine exerts on a object
the output work times the input distance
What is effort (input) distance?
the force required by a machine in order to accomplish work (the force you put on the machine)
the force which an effort force must overcome in order to do work on an object via a simple machine.
the distance an input force acts through
the output work times the input distance
What is resistance (output) distance?
