I am currently working on designing a linear brake/lock for a completely different purpose but it will be based on the same principle as in a quick clamp shown below. Before building a prototype I do want to make some rough calculations to check dimensions, angles etc. etc. However, I am for some reason struggling with the calculation and can't seem to get it right.
You can see my figure below. Assume no friction from applied forces Fpull and fspring (that is why they are not hypotenus)
My question is. How can I easily check whether or not the locking will hold a specific Fpull-load with given geometries and input data as shown below? I would like to create a an excel spreadsheet. Perhaps should one find at which friction it would hold instead?
h1=20
h2=40
h3=20
Fpull=7000N
friction=0,3 (should this be an unknown instead?)
Fspring=50N
Beta=5 degrees
I would greatly appreciate any feedback on this problem. It should be fairly simple I think, but I am caught in a thought loop on this.
