Hi @Tom.G and @BvU . Based on the Above details can you please formulate the equations and diagrams to help me solve the problem. Thank you.

Hello @BvU and @Tom.G . Thank you for your inputs and support to help me solve my problem. Please see attached the document with detailed information on the system and its working. Can you please take a look and let me know. Thank you again.

Hi BvU. Thank you for the reply. The total length of that link(leg) is 83in (51+32). There is a smaller telescopic tube (23 inches long,sorry for not providing that length before) inside the 83 inch long leg which pivots at point 1. The fixed end of the gas spring is connected to the smaller...

Hi All, I am working on this linkage mechanism. Please see the attachment for images. There are 3 pivot points. Two of which are connected to the ground. The" Inside Leg 1" is telescopic to "Leg 2" and has a 120 LB compression gas spring connected at mount points as shown in the image. The leg...

I do have a basic understanding. But not a very in depth knowledge of it.

Arm1 and arm 2 are parallel. the lengths are specified in the image. This is all the information I knew put in. Could you please guide me from here. @Dr.D @jrmichler

@Dr.D No they are not fixed at the right angle. They bars are parallel and are intended to be moved from the fully extended position to the lower position as shown in the photos. That is the only range of motion I am looking to achieve with this mechanism.This whole thing can be assumed as an...

Thank you all for your replies. Apologies if the diagram wasn't clear to understand what I am looking for. @jrmichler Yes the whole system is at a conceptual stage. The only know quantities are the weights of all the parts. You suggested me to define the motion of one part and hence calculate...

The attached image shows a linkage mechanism with 2 parallel bars pivoted to a fixed base. The lengths of the the bars are equal. A connecting linkage and gears are used to connect it to a 3rd bar. I would like to know how to analyze this linkage system to find the forces, moments and loads for...

Thank you all for your valuable suggestions to solve this problem. This solves part one of my problem. The part 2 just as specified by anorlunda would be to figure out the force required to lift the pawl. That is the force being exerted by the pawl on the gear wheel teeth. How to calculate the...

Hi, I have strap ratchet which is being pulled on both sides with some force(say 500lb). Could some one please help me know the force to be applied on the handle of the buckle to open it? Can anyone please help me with the math in this problem. The ratchet is being pulled by webbing straps on...
