Force pressure variance after hole is plugged?

In summary, there is a tall cylinder filled with water, with a 3 inch diameter hole near the bottom that is constantly being refilled from the top. To stop the leak, a 10 inch long cylinder of perfect diameter is pushed into the hole with X amount of force. The question is, how does the force required to keep the plug in the hole compare to the force needed to initially push it in? And does it take more, less, or equal force to push the plug deeper into the hole compared to keeping it in place? This concept can be further explored through the use of a hydraulic ram.

TL;DR Summary
what is the force delta to plug a leak in a vessel vs the force to maintain the plug after it's in place?
There is a tall cylinder filled with water. And there is a 3 in diameter hole near the bottom and water is gushing out. (assume the cylinder is continually being re-filled from the top)

You work to plug the hole with a 10 inch long cylinder that is exactly the perfect diameter fit to plug the hole. (Assume a perfect fit with no wall friction as it slides into place)

It takes X amount of lbs of force to push the cylinder plug into the gushing hole to stop the leak.

Question -
How much force does it take to keep the plug in the hole once it has been pushed in vs the force required to get the plug in the hole initially?
(meaning, is it "easier" to keep the plug in the hole once it's inserted?) (equal to, less than, more than?)

Does it take more, less or equal force to push the plug deeper into the hole vs the amount of force to keep it one position?Thank you!

Is this homework? What do you think the answer is/what have you tried?

FAQ: Force pressure variance after hole is plugged?

What is force pressure variance after a hole is plugged?

Force pressure variance after a hole is plugged refers to the change in the amount of force or pressure exerted on an object or system after a hole has been filled or sealed. This can occur in a variety of situations, such as in hydraulic systems, structural integrity of buildings, or even in the human body.

How does plugging a hole affect force pressure?

Plugging a hole can affect force pressure in a few different ways. In some cases, it may reduce the overall amount of force or pressure in a system, as the hole was likely causing a leak or decrease in pressure. In other cases, it may increase the force or pressure, as the plug may be adding additional weight or resistance to the system.

What factors can influence force pressure variance after a hole is plugged?

There are a few factors that can influence force pressure variance after a hole is plugged. Some of the most common factors include the size and shape of the hole, the material used to plug the hole, and the surrounding environment or conditions. Additionally, the type of force or pressure being exerted and the overall system design can also play a role.

How can force pressure variance after a hole is plugged be measured or calculated?

Force pressure variance after a hole is plugged can be measured or calculated using various techniques, depending on the specific situation. In some cases, it may be possible to use pressure gauges or sensors to directly measure the change in force or pressure. In other cases, mathematical equations or simulations may be used to estimate the change based on known variables.

What are some potential consequences of not addressing force pressure variance after a hole is plugged?

If force pressure variance after a hole is plugged is not properly addressed, it can lead to various consequences depending on the situation. In some cases, it may result in further damage or failure of the system, as the force or pressure may continue to build up. In other cases, it may cause imbalance or instability, which can also lead to potential hazards or accidents.
