Wheel vs. lever...

[iacob alex]

...can be a Delphic,ambiguous,not well undestood main way "pointer",  that can be used when we think and try to imagine "something  self moving" ...you know...About wheel-symbol we know a lot,but about lever?Basic mechanics is lever,the wheel comes ...after.Simply,the weighing machines as mechanical devices for comparing two masses in gravity,acts as levers,not as wheels.A wheel is an evoluated lever concept,but his summary equivalent is a lever also.A weighing machine it's a comparison ,a setting side by side device that plays gravity to mesure mass in gravity.So,if we want an ever unbalancing weighing machine,let's unbalance them in some manner so to keep on turning:vibrational(decreasing balancing) mood transformed in an acceleration mood.A gravity "squatting" pair of torque on a slightly modified weighing machine.You can begin with a steelyard:a fulcrum,a stick and a sliding mass, as the old Roman balance.A simply game.All the Bests!/Alex...an Inertial Sailor

Hello "sailor" -without haven",
The ,now death,german inventor Bierner DE3621312
and the british inventor Frederick A. Knapp GB365209
used the wheel/lever-principle !

Probably an idea-"to find your haven"!

...is the real problem.So, vs.=versus,you can find in "Webster's Dictionary" as "in contest against,in contrast with,by way of alternative to...". The  problem,introduced at this forum topic, was "wheel vs.lever",or lever in comparison(facing,in exchange for,opposite to,contrarly to...) with wheel.Most people think(or dream) about  "something" as a self-turning wheel due to gravity.Few people,as I know Bessler only,designed and accomplished a different concept:a lot of unequally levers that balance in a certain manner on the spokes of a wheel,so that this one is self-moving in the and owing to gravity.So history tell us and Prof. Evert(  www.evert.de   ) explains in a so clearly,inteligible german thinking manner (text,drawings,animations) this case:wheel and lever(s) concept.Now,our friend, de Lanca ,I have a question:you know about Knapp and Bierner...what were  their concept?Wheel(1),wheel -lever(2) or lever(3)?My proposal was "lever only"!By the way,as an "old sailor" I have some sheltered ancorages,safe waters...Smile!All the Bests!/Alex

...seems to be this wheel concept on our endeavour to imagine a gravity power pulling out mechanism,device.Really ,the gravity,this natural rush,overflow,cascade is setted in a very "difficult" situation when "meets" our wheel type arrangements,a kind of no more that stable balancing "traps"...useless regarding to our expectations.Gravity "rapids" property has no time to manifest his impetus(m*v):we have the balancing  mass(es) on a comparating tool,as usually  ,but with no velocity.The outcome is no impetus.It's a weighing machine,nothing more,a failed "start" for a self turning mechanism.A proposal,a solution can be to set free impetus,thinking about an other,unlike  aspect of the weighing mass,comparator.As in electricity we need that momentary surge in one direction of voltage or current,in mechanics we demand for that "unseen in the air" change in momentum effected by gravity about a mass,by the TIME during which it acts.So,let's free the gravity momentum... can it be a manner to understand clearly,to achieve a turning gravity "waver"?Who knows?Usually we understand what we know,only.That's normal in our transitory life:a patient attention ask for time...All the Bests!/Alex

...that old  "dream" of mechanics, is a little like the swing sets you might remember from our springtime of life.Swing gives us an emotional,sympathetic contemplation to this gravity...all life we live in,a feeling of a kind of real flight...in an amazing, ineffable,beyond words medium,environment... but in a controlled manner however.You can play pendulum,alone or lever,with a playmate:you pump your legs,so to increase the height of the swing's arc(you can make it as a circle...with some bravery,tenacity),that's all.Simply thinking,it's  like we charge-discharge ourself with "something".In fact ,we perform a lever concept:a fulcrum,a bar ,setting side by side in comparison two masses:one "fixed" and one "mobile".If we can swing "on the spot" , why not imagine a lever rolling in the same pattern, pumping some "leg"?I said rolling,so for a full round,circular "trip"...we ask for some help(impetus) in a line  that falling power>lifting use up.That motion of "pumping legs" can be transfigurated,reconstructed in a "pumping lever",or playing elementary mechanics.Gravity exibits in a restrictive path:downward only.We can fall in many ways,inclusively on an inclined plane.If we want a self-pumping alike motion, regarding a swing-lever style,let's place the moving mass on an inclined plane ,so that at the bottom position,it falls to the fulcrum(brings about the short arm R1) and at the top position,it falls from the fulcrum(brings about the long arm R3).This switching mass M1(and arm) has a  fixed arm companion mass M2,positionated   at R2 from the fulcrum and R1<R2<R3 , M1=M2.Now,can we have a rolling lever on the spot?Can we make it self?Let's hope!All the Bests!/Alex
