Looking to achieve opposing mechanical forces.

AI Thread Summary
A user is designing a piece of furniture featuring opposing stairs that raise or lower a central platform, requiring collaboration between two people to maintain balance. They propose using a pulley system to elevate the platform when a stair is stepped on but seek advice on creating downward force for both the stairs and the platform. The concept is likened to a pyramid with a flat top, and the user expresses enthusiasm for exploring this unique design. A suggestion is made for the user to provide a visual representation to clarify the idea. The discussion revolves around innovative mechanical design and collaborative interaction.

Hi Everyone.

New to the forum

I am attempting to design a piece of furniture that has opposing forces. A set of opposing stairs that either lower or raise a central platform. The idea is that two people would have to collaborate together to make sure the central platform doesn't sink. Think of it as a pyramid with a flat top (this being the platform) with stairs either side. Currently I understand that a pulley system could be used to raise the platform once a stair is stepped on. But how might I achieve downward force with both a stair and the platform?

Bit weird I know. But perhaps fun to explore.

Welcome to PF!

Can you draw a picture of this? I'm having trouble picturing it.

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...
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
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...
