Mechanical advantage device

A force transducer is a mechanical arrangement for changing a character in relation to their point of attack, their direction or their amount.

The simplest power converter are ropes, rods, reels, inclined planes and levers. These are also the basic simple machines.

Cables, rods and levers to change the point of application of force because the force is no longer applied to the object itself, but at some distance.

Levers, inclined planes, and loose rollers act also amount changing.

Solid rollers act in combination with ropes on the direction of the force without changing the amount. Loose Wheels, which are combined with ropes, called tackle. This also causes a change in the amount of force.

According to the energy conservation law and the golden rule of mechanics a force transducer can be the product of force and displacement, so the work unchanged. So one needs, for example by using a lever, only a quarter of the normally required amount of force to lift a load, as this is associated with a fourfold increase in the stroke. If necessary. However, to be expended due to friction slightly more force.
