Give the definition of the term “mechanism”.
What types of bodies can incorporate mechanism?
Let's imagine: we have an electric drive before us.
How can you subdivide it?
What types of mechanisms can you find in its structure?
We can see a lot of constructions around of us. Can you give the
distinctive feature of mechanism?
Is “The theory of machines and mechanisms” a science? Is it difficult?
Why is it necessary for mechanical engineers?
What are the purposes of studying this discipline?
What can you say about structural and kinematic analysis of mechanisms?
List the types of links you know.
Give concepts: kinematic pair, link. Tell about principles of kinematic pair
classification.
Give the definition of a kinematic chain. Tell about the classification of
kinematic chains.
What is a motion freedom of the mechanism?
Tasks for seminar:
1.
Classify the links of the mechanism. Give classificational characteristic
of the mechanism itself
according to models, analysing the character of
links movements.
2.
Classify kinematic pairs according to character of relative movements
and according to the classes. Describe movements. (
Cards in Appendix
II.1
).
3.
Give the classification of mechanism and their links using the picture or
scheme of mechanism. Explain. (
Cards in Appendix II.2).
