I am designing a joint which I want to break at a specific force. I want to design a 2 parts connected by a joint that breaks when a certain amount of force is applied and thus prevent any damage to those individual components themselves. I also want the joint to be easily replaceable without replacing the individual parts themselves. I'm hoping to 3D Print the joint.
I have seen some petrol stations that have pipes attached such that they will break and cut-off fuel supply if they are pulled harshly(i.e. By someone who forgot to take the nozzle off their car and tried to drive away). I don't know the name of the mechanical linkage they use. But I'm hoping to achieve a similar affect.
I would appreciate if you could point me to relevant information sources and design of such type of linkages.
