Confirm Formula to calculate force in simple door application

A proposal has not yet been provided

I am a mechanical engineer. I also teach physics and math at high school and college level and visiting lecturer in fluid, mechanics of material, dynamics and energy subjects. I have 5 years’ experience in teaching. Also I conduct an educational institute and large number of teachers work under me who are from various disciplines. Therefore I can do your work accurately. Inbox me for more details

Hi, I am a mechanical engineer with master’s degree as well. Currently, I am teaching machine design courses in an Engineering University. I want to make my reputation here; therefore, I will definitely give my 100% to any job I get. I assure you best work within the deadline. Thanks.

PhD in engineering. Large experience in design. I will be glad to help you. Please send a message back to establish the details.

Hello, Force is varying with respect to amount of door opening. max force location is at end as you expected. Same thing can be proved with some software. I can do these things if it offered for me. Regards Jagadeesh

I am a new member but I have 3 years experience on design mechanical products. I am working on R&D Department and I usually design mechatronics systems using hydraulic cylinder (it is same same with your problem). I view your attached file and calculated your model. The result of Ao is right but the force need to open the door is wrong. My result: F= (Mass of door x 9,81 x w/2 x Ao) / (Number of Actuators x (x-v) ) I am a new member so I need your project to improve my CV. Thank you!

I am a mechanical engineer and I can confirm this the same day. I will provide instant service for your request.

I am a Mechanical Engineer. I can check the formula. From your sketches it appears that the force required at the initial closed position will be highest. and thereafter the force required to further open will reduce. I will go into all aspects and give you the answer in the shortest possible time
