Hydraulics: Push Force vs Gravity Force?

AI Thread Summary
Hydraulics apply different forces when pushing a mass away from or towards the ground. Gravity assists the hydraulic force when pushing down, allowing for potentially lower force application, but this effect is minimal for heavier loads. For significant weights, like a 50kg pole with a 100-tonne ram, gravity's influence is negligible. However, with lighter loads, such as a 1kg mass, gravity's effect becomes more noticeable. Overall, while gravity plays a role, it is less impactful in high-force hydraulic applications.

Just have a question about how hydraulics work...
When a hydraulic pushes a mass away from the ground, does it apply the same force as to when it pushes the same mass towards the ground? I'm wondering if gravity assists it when its pushing it towards the ground and therefore can apply a lower force. Is this right?

Of course.
 
Gravity assists, of course, but for 'reasonable' loads it is insignificant compared to the force of the ram. If you're driving a 50kg pole into the ground with a 100 tonne ram, gravity really doesn't enter into the picture. On the other hand, a 1kg ram in the same situation would be much less noticeable in comparison to gravity.
 
grAVITYH WILL cause friction here its only affects on the case of lifting
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
