Question 1.
Define a dyad and its role in mechanism synthesis.
Show hintHide hint
Think about basic linkages in mechanism design.
Question 2.
What is the objective of motion generation?
Show hintHide hint
Focus on the importance of coupler positions.
3Question 3.
What is the main focus of two-position synthesis?
- To locate a point in three positions
- To design a mechanism that oscillates
- To find a dyad that places a point in two desired locations
Show hintHide hint
Remember the main objective of two-position synthesis.
4Question 4.
True or False: The crank-link in a crank-rocker mechanism can rotate fully.
- True
- False
Show hintHide hint
Consider the role of each link in a crank-rocker.
Question 5.
Given three prescribed positions for a coupler point in a four-bar linkage, design a graphical method to determine the necessary linkages and joint centers.
Show hintHide hint
Remember the geometric techniques we discussed for relative positions.
Question 6.
If a crank-rocker mechanism experiences stress during operation, how would you reassess the design to maintain functionality without compromising structural integrity?
Show hintHide hint
Consider both material selection and redesign principles.
