Since we know by conservation of energy that no machine can output more energy than was put into it, the ideal case is represented by a machine in which the output energy is equal to the input energy. For simple geometries in which the forces are in the direction of the motion, we can characterize the ideal machine in terms of the work done as follows: Ideal Machine: Energy input = Energy output
Work input = Fedinput = Frdoutput = Work output From this perspective it becomes evident that a simple machine may multiply force. That is, a small input force can accomplish a task requiring a large output force. But the constraint is that the small input force must be exerted through a larger distance so that the work input is equal to the work output. You are trading a small force acting through a large distance for a large force acting through a small distance. This is the nature of all the simple machines above as they are shown. Of course it is also possible to trade a large input force through a small distance for a small output force acting through a large distance. This is also useful if what you want to achieve is a higher velocity. Many machines operate in this way. The expressions for the ideal mechanical advantages of these simple machines were obtained by determining what forces are required to produce equilibrium, since to move the machine in the desired direction you must first produce equilibrium and then add to the input force to cause motion. Both forceequilibrium and torque equilibrium are applied.
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
Force transducers are also commonly recognized as force sensors. A force sensor is described as a transducer that converts an input mechanical force into an electrical output signal.
output force is al ways less than input force

the force can be used with the mind
First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.

input force is force exerted on a machine
An output force is the force that is exerted from the input force to create motion of the resisting object. the input force can be less or more then the output force
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.
Input force is the amount of force that is put on another object. The input force is measured in Newtons. Pressure is the common element found in input force.
You measure input force with the formula F = ma. Input force is defined as the force that is exerted on a machine or the force that you put on something.
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
