for molding and dies with a diferent system, impact/punching by solid material or pressing by hydraulic system of course i need to understanding. the diferent calculation. For the impact/punching machine, I need to know how much force needed for mold to punching the dies or on the hydraulic...

yes, because on the hydraulic system, it was the Newton #1 law that working on it.

yes, for the 1000lbs i put on the effort-side, it pushed me back with 1000lbs. meanwhile on the other load-side, there was 9000lbs lifted up by the system. overall the Earth pushing back 10.000lbs as reaction for action given by the system on the lever

Thanks Menor Nugatory, yes, that's my yesterday problem, i got little confused betwen force and pressure. where F=MA and Pressure P=F/A. because both are "action" that able to move an object

sample on lever system https://www.physicsforums.com/attachments/lever-gif.82234/ the force we put in effort arm is 1000 lb, it lift 9000 lb. it doesn't me we spend 10.000 lb, but the fulcrum representing the reaction of 10.000 lb from the lever.

What i found that Newton #3 law not precisely work on hydraulic system because it has a Mechanical Advantage where there was an exchange distance and force as result. but it work precisely on punching and molding machine, because it was a solid material. and yes the force per cm2 on the molding...

Like Isaac Newton last words Sir Isaac Newton, British Scientist; died in 1727: 'I don't know what I may seem to the world. But as to myself I seem to have been only a boy playing on the seashore and diverting myself in now and then finding a smoother pebble or prettier shell than ordinary...

yes, because the lever is a solid material, imagine the down side of the fulcrum is the mold, the Earth surface is the punching area as the reaction, the lever is the force as the action. The lever representing the Mechanical Advantage of a simple machine

Yes, the thing happened is MA (Mechanical Advantage) shorter distance as a trade of biggest force. but my "yesterday" problem is about Newton #3 Law, force on action and reaction is equal. and i found the clue is the law work on solid system

See the force on the lever. on one side it force (action)100 N. And by the MA (9:1), the force in other side (reaction) is 900 N. ...and of course it didn't mean we put 1000 N to the level. because it sound false. this is not the Newton #3 law. this is Mechanical Advantage like on hydraulic...

like a christ comes for a sinner, so a physics comes for dumbber. so i love it both. as a dumbber it keep me learning, and physics is a great way to finding that we are dumb.

I like Physics, but i dumb. and i love it.

Thanks new friends. last night "struggling", finally comes with result, Newton #3 law is work on solid material, because no mechanicl advantage there to be trade. The force is equal, like been used on punching machine. No matter the different size from input and output area, the force remain...

Hi Cruz. First of all to learn language is knowing everything around you by the new language you want to learn, in this case germany. my japanese friend have a mini dictionary he made it by him self. it contained: - every part of you body.. from hair to foot - everything around your bedroom...

Hi Mentor i am in little confusing about force, according Newton third law force on action and reaction is equal but according hydraulic system are not equal. https://www.facebook.com/photo.php?fbid=1749685448591067&set=pb.100006488851023.-2207520000.1429362639.&type=3&theater Thank you for...
