How Is Deflection Calculated for a Partially Supported Circular Lid?

AI Thread Summary
The discussion focuses on calculating the deflection of a partially supported circular lid being lifted by a linear actuator. The lid weighs 30kg and has a diameter of 380mm, with support provided by only one-third of its area. A 60x20x180mm plate is mounted to the lid using four M10 screws to facilitate the lift. The actuator has a load capacity of 1500N and is used to lift the lid to a height of 100mm. Participants are encouraged to share diagrams to clarify the setup for better understanding.

Hi
In one of my application I am using a linear actuator to lift a 30kg lid which has a diameter of 380mm.
I can only use 1/3rd portion on the lid to take support, for actuator which I used a 60*20*180 long plate mounted to the lid and lift.

Welcome to the PF.

Can you post a diagram of your setup? It's a bit hard to understand your question (at least it is for me). Thanks. :smile:

Hello Berkeman,
Thanks for your reply. Here is the image
I have attached, the plate is mounted to lid using 4- M10 screws and the lid is lifted to 100mm length

Thanks in advance:smile:

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 '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

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...
