You are offline. exact (3) Therefore, when both Finger 4 and Finger 3 rotate to a prescribed angle, Finger 4 is released from mechanical constraint and automatically moves back to the stand-by position which corresponds to the location of the edge of card block. The Examples of constrained motions in classical mechanics abound. 17-25 To . Severe local heating and the mechanical constraints caused by the initial tack welding or clamping of parts to be arc-welded create undesirable residual stress or distortion in the parts. As these objects move, the user can constrain their motion with his or her hands, or many other kinds of physical objects. Design constraints are conditions that need to happen for a project to be successful. There are two different types of constraints: holonomic and non-holonomic. Mechanical Constraints as Computational Constraints We can easily understand kinematic pairs once we understand the concept of degree of freedom. Biological constraints are factors which make populations resistant to evolutionary change. In our work as PCB design teams, though, we also consider board constraints. In this chapter we will only consider time-independent constraints.
