# Lever case 2

Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity.

It is also called speed multiplier lever. It is common to call the input force the effort and the output force the load or the resistance.

In this paper, the normative version will often be more appropriate, since equilibrium-conserving manipulations of configurations of masses will be in the main focus. For example when counting the planets of the solar system, the actual planets may stay where they are; it is sufficient to consider them as planets in order to count them and to determine their number. It is also true that the conclusion of this syllogism can directly be seen in the general premise, the latter being understood simply as a conjunction of all special cases. It is common to call the input force the effort and the output force the load or the resistance. He stressed that this context is situated in daily life and paid special attention to manual production procedures like the so-called three-plate procedure in the production of steel planes. This is a descriptive law which can, however, be translated into a normative rule by saying that reciprocal displacements of weights on both sides of the fulcrum do not disturb equilibria. Hence the criticisms Mach directed against the famous Archimedean proof of the Law of the Lever should be considered as invalidated. This hierarchy indicates a qualitative difference between the premises and the conclusions—a difference which is bridged in deduction. However in an oar the load arm is greater than the effort arm, and the mechanical advantage is less than one.

Mechanical advantage may be greater than, less than, or equal to 1. This text illustrates, as Beisenherz and Renn et al. Certainly it is impossible to maintain that all men are mortal without already asserting that the man Socrates is mortal.

He does not deny that the conclusion is contained in the premises—and how could he have done this? Indeed, in counting, one brings together the objects counted simply by successively considering them.

As Vailati Vailati, Dijksterhuisquotations from the second English edition Dijksterhuisand Renn concordantly argue, the Archimedean proof was essentially based on the notion of the center of gravity, that is, according to Dijksterhuis, on the premise that the influence exerted on the equilibrium by a body suspended on a lever is judged exclusively by the gravity of the body and the place of its center of gravity, and that the shape is immaterial [Dijksterhuis] and consequently that a lever equilibrium is not disturbed, if one of the suspended magnitudes is made to change its shape while preserving its weight and center of gravity.

The lever operates by applying forces at different distances from the fulcrum, or a pivot.
