Mechanical Oszillating Ciruit Objectives

This chapter will show relations between effective principles of Bessler-Wheel and known aspects of mechanical swing circuits. These points of view will complete knowledges of Remote Viewing above. Harald Chmela pushlished at NET-Journal May/June 2001 an article ґOszillations and Resonancesґ, which also is available at his homepage (see External Links). Conciderations there were important hints for me. Following parts of this article (shorted) describes build up of pendulumґs oszillations. Amplifying oszillations

... By example of pendulums we assumed, swinging movements must be started from outside. However, how can kids achieve oszillations while sitting on a swing? Thatґs a case not to explain by Newton's laws. Cause there, each force must show a counter-force same amount. At a swing thatґs not possible, cause there is no mechanical connection for counter-forces. Supporting point will take only weight forces, all other forces should have to equalize each other. Nevertheless itґs possible to accelerate amplitudes by periodic changes of a parameter of a oszillation curcuit. These changes must correspond to phases of swingings, so they will be build up further on. Thatґs also valid for pendulums resp. a swing, cause these are mechanical oszillators. Parameters defining frequence of swinging here are length of pendulum (position of mass-center) and gravity power. As gravity is constant, amplifying can only be achieved by changing position of masses, so by sensefull shifting of weight. Each kid can manage this without theoretical explanations. In order to make a swing swinging, input of energy is demanded. Energy is force multiplied by lenght. As a distance here is only possible to shift center of body. However, forces nowhere can be supported. Itґs only the centrifugal force, which could be counter-force demanded, thus to make energy effective. When the swing is at its position most downside, one will start to lean back, so center of mass is shifted downward. When the swing will reach its maximum sideward postition, one has to straighten up and keep up center of mass until swing will go back down. Then will follow same procedure in backward direction. However, only qualified swingers can manage also that second work cycle. If masses are shifted well, mass center will move at an eight-shaped track, relative to its middle radius. So one can recognize an essential characteristic of parametic oczillations: different frequences of amplifier and oszillation curcuit. This swing must move ahead and back as a periode. Same time that mass-point must do two periodes by relative movements up and down. Quite downside, centrifugal forces are strong, so weight automatically is pulled down. At the end of swinging, centrifugal forces are small, so straighten-up can be done easy. Only by phases shifted, mass lowest position and swingґs lowest position are at different locations, energy can be transfered. When this swing will work without friction, energy will be transfered only from mass to swing and back again. One may imagine, mass-point is fixed at a spring and moved by centrifugal forces. Mass then will move at U-shaped track, same frequence like the swing. Both lines of that eight then are shifted to one single curve. Only for input of energy in order to build up swinging, double frequences will again be demanded. Thatґs practically that asymmetry, by which energy can be transfered.

Harald Chmela is an expert in electronics, showing lots of interesting experiments at his website. Analog to electronic oszillation curcuits, here he described essential parameters of mechanical oszillation curcuits. At the following, I will add some aspects by my point of view. Stabile and labile

At picure EV SKM 01 a swing is shown schematically. Around an axis (SA, system axis) is installed turnable a pendulum (RT, rotor arm, German Rotorträger). On the seat of this swing (RA, rotor axis) a person (RO, rotor) is sitting. At starting position (A) that person is in a stable situation most down below system axis. Center of mass (MP, mass-point) of this person however is in labile position in relation to its support (RA). If now this person lets ґfallґ himself some backward (B), the swing will move ahead. Mass-point will move to its downmost position and this swing movement will go on some distance (C). As Chmela mentioned above, now the person has to straighten up into a position parallel to radius. Mass-point has to be move most near to turning axis, here e.g. also by draw up of legs. While swinging back, the person may keep this position, thus at the end of that phase the pendulum (here left side) will show same amplitude. At this picture below, situations are shown by larger amplitude. While swinging here at this swing, most large difference of heights (potential energy) should be transfered into kinetic energy. Thatґs achieved, when the mass-point (from D to E) is moved to larger radius. So mass can fall as deep and long as possible. Building up of swinging resp. masses reaching higher up, however can only be achieved by input of power. This person does this workload, when moving mass (versus centrifugal forces) most near to system axis to the end of upward phase (from E to F). Kinetic energy (resulting from downward phase) by that is brought to a smaller radius, thus angles-speed will be accelerated correspondingly, thus a position higher than the starting position will be achieved (mass-point at F is some higher that at D). Workload

By this procedure of movements, this person has to do two jobs. Below (at E) this person with his arms has to hold his weight and in addition strong centrifugal forces. This work is sensefull (cause larger radius is achieved), but will not build up swinging in direct manner. In upward phase, this person must lift up its weight into a position parallel to radius. Mass must also be pulled counter centrifugal forces, which here however becomes weaker. Nearby maximum swinging up (at F) this workload can be done easily, cause there mass practically is ґwithout weight and forcesґ. Work at that moment will bring effect of building up swinging in direct manner. Now the job will be, to let centrifugal forces do all workloads. Building up swinging at backward movement is rather difficult, so a procedure moving ahead all times would be better. As an example, this is possible by a ґlooping swingґ, schematically shown at picture EV SKM 02. Looping swing

Around system axis (SA) again this rotor arm (RT) is installed turnable. Effective mass (MP) is fixed on a rotor (RO). Both arms are connected at the rotor axis (RA). That red circle there marks, however here this connection is build by a spring (diverse technical realizations are possible). At this picture this assembly of parts is shown at different positions while turning. Turning sense in generall here is counter clock-wise. Green curve marks the track of effective mass. Upside (at 12 oґclock) angles speed is minimum, so only small centrifugal forces will exist. Weight of mass weights down at the spring. A relative small angle will be between rotor and rotor arm. At further procedure (starting about 11 oґclock) by the weight will be started falling-down-phase, thus turning speed will increase. Force of weight and centrifugal power now will build a resulting power directed more and more outward. So the spring will be expanded (nearby 9 oґclock). Downside (at and behind 6 oґclock) weight and centrifugal forces will add into vertical direction, so there the spring will show maximum tension. A rather large angle will be between rotor and rotor arm. When effective resulting forces of weight plus centrifugal power will decrease (nearby 3 oґclock), tension of spring can move mass back inside. To the upside starting position, so mass will be brought back to much smaller radius, which will effect building up of oszillation as discussed above. Working centrifugal forces

With this technic, holding weight (counter gravity and centrifugal forces) is transmitted into tension of the spring, while mass is still allowed to move into centrifugal direction. Energy thus stored, some time later will effect centripedal movement of mass. So ґunproductiveґ work (at phase of swinging downward-outward) is changed to productive work (transfering kinetic energy into faster angles speed). Also Harald Chmela above did talk about a spring, which would lead to U-shaped track of mass. If however a usable power-component shall be achieved, there must exist asymmetry. Here the spring does not only work in radial directions, but mass is also moved back and ahead in relation to turning sense. So instead of symmetric U-shaped track, here an asymmetric oval track of masses is achieved. By backward-swivel-movement in downward phase, the mass comes to larger radius, without decelerating turning of rotor arm. Increasing tension of spring, above this will effect a positive turning momentum to the rotor arm. However, this is equalized by following release of the spring. At the upward-inward phase however, that swivel-motion-ahead will accelerate angles speed of rotor arm. As Chmela theoretically did show above, an eight-shaped track of mass must be achieved in relation to average radius. As here is no backward phase, but phase-ahead will follow phase-ahead, track must be (half eight, thus) S-shaped. This kind of spring here will do that job, cause upside (and some downward, nearby 1 oґclock to 9 oґclock) weight will compress the spring, afterwards the spring will be expanded (until lastly will move back to normal position). So if a kid will be able to amplify a swing, this technic will produce continuously looping pedulum. So this simple technic represents behavior of a person on a swing building-up. It would be fine, if anyone could approve this effect by real experiments. However it will be neccessary, relations of lengths of arms and effective masses and characteristics of springs are well coordinated (otherwise machine will hop - like Besslerґs unsuccessfull attempts). It would be interesting task for students of technical subjects to write simulation programs in order to optimize this process. Viewing

By this simple animation procedure of movements are shown, only by one assembly. At Bessler-Wheel some (probably seven) of these assembled parts were installed. It might now be interesting for readers, whether and how viewers of Remote Viewing sessions above did describe this construction. Certainly, not all elements demanded here are integrated by now. By viewing into ґBesslerґs workshopґ also these outstanding parts should be to design. At following chapters some of these additional aspects will be discussed.
