Beginner trying to understand DS jack and force

[medesign1]

Currently in the process of learning DS in Inventor. I came across jack in unknown force and I am not sure what to make of it. How is it different from an unknown force and how do I use the data I obtained from an unknown jack?

Thanks

None of those seem to define what a jack is compared to a force. That is what I need rather than a intro on how to use it.

Force is a user input applied load.

Jack is a resultant output calculated force between two defined points.

But what about unknown force? isn't also the same as unknown jack?

OK, now I have no idea what you are referring to.

Do you have some screen shots to illustrate your questions?

Do you have some Inventor files to illustrate your questions?

What book are you using to learn Dynamic Simulation?

What (shudder/whimper) youtube links are you using to learn Dynamic Simulation?

Essentially, since jack shows with two arrows, is jack just the magnitude of the two forces combined?

Equal and opposite reaction force.
