Hi. I have some Problems in solving a problem. I'd be so glad if someone could help me with this.
Assume that there is a Force (F) which is affected on lever1 and the hand shows something and then the system doesn't move (this is a statics problem!) we know all the lengths and neglect the mass of each part. and assume that we know the coefficient of springs(name them whatever you want!).
the questions: 1. what is number 3? is it a kind of spring?
2. could you please draw FBD of each part of the system?
Here is the picture:
