5 cards from this section. Quick, good the night before a test.
What does DOF stand for in mechanical systems?
Think about how you can describe a mechanism's configuration.
What formula do we use to calculate DOF for planar mechanisms?
It involves links and pairs.
What does DOF indicate in a mechanical system?
Think about how we define motion.
Grashof's Rule tells us if a mechanism can fully rotate.
Recall the linking conditions.
Design a mechanism with 5 links and determine its DOF when there are 3 lower pairs and 2 higher pairs.
Input the values carefully into the formula.
You have a four-bar linkage with link lengths s=2, l=5, p=3, and q=4. Determine if it is a Grashof type and explain why.
Always analyze the inequalities.
