 What will happen to a pneumatic cylinder if you pressurize both ends With the same amount of pressure At the same time. I've built this small pneumatic circuit to illustrate this I've got point one five megapascals, which is approximately equivalent to 22 pounds PSI a normally closed push button and a T in line between my cap end and my rod end To demonstrate what will happen If you energize both sides of the cylinder at the same time the cylinder extended Logically you would think that if you put the same amount of pressure on both sides at the same time that it wouldn't go anywhere This gives you a physical demonstration of the relationship of the fluid power triangle which will have force pressure and area and how they coexist with one another
