3.1.2. Method

Try these first

1. 1.

   Define a dyad and its role in mechanism synthesis.

   Hint

   Think about basic linkages in mechanism design.

2. 2.

   What is the objective of motion generation?

   Hint

   Focus on the importance of coupler positions.

3. 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

   Hint

   Remember the main objective of two-position synthesis.

4. 4.

   True or False: The crank-link in a crank-rocker mechanism can rotate fully.

   • True
   • False

   Hint

   Consider the role of each link in a crank-rocker.

5. 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.

   Hint

   Remember the geometric techniques we discussed for relative positions.

6. 6.

   If a crank-rocker mechanism experiences stress during operation, how would you reassess the design to maintain functionality without compromising structural integrity?

   Hint

   Consider both material selection and redesign principles.
