How Is Deflection Calculated for a Partially Supported Circular Lid?

[Rajashekar]

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.

How to calculate the deflection of lid when lifted to 100mm

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.

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

The lid weight is 30kg, the actuator load carrying capacity 1500N.
