I've been confused for awhile about this and I haven't found any decent explanatory answers. I read somewhere that the general formula for finding the force exerted by a solenoid electromagnet could be found by: Force = ((N x I)^2 x k x A) / (2 x s^2) where N is number of turns of a...

Yes, its true that air pressure acts in all directions but if, in this container, let's say a cuboid for hypothetical purposes, 5 of the 6 sides are completely sealed and one side is a movable surface, the force would act on all sides but would only have a real effect on the movable surface. I...

If a body,let's say a big block of steel, has a net downward force of weight of 1000N, would it be possible to lift the block using air pressure? I mean, if you put air in a completely sealed container with a movable piston on top and you pressurized such air to an appropriate pressure, then by...
