Answer the following

2. Modeling and analysis involve developing CAD model of the design and analyzing it in virtual environment (computer) (Y/N)

3. Selection of the best design out of a number of viable designs can be done using:

a. Hit and trial method

b. Decision matric

c. Considering only one important factor

4. A kinematic chain cannot have quaternary joints (Y / N)

5. Planar mechanisms have motion in the same plane (Y / N)

6. The degree of freedom or mobility of a mechanism can be calculated using Gruebler's and Kutzbach's condition/ equation (Y / N)

7. A roller sliding contact is considered as half joint (Y / N)

8. Link is the basic unit element of a mechanism (Y/N)

9. Link is not considered as rigid/ resistant body in the study of design of mechanisms (Y /N)

10. One way of reducing cost of a product is to use standard sizes (Y / N)

11. Mechanics is the physical science that deals with the objects in motion only (Y / N)

12. Screw pair is a type of lower pair (Y / N)

13. Higher pair involves surface contact (Y / N)

14. The design process does not involve iterative steps to improve design (Y /N)

15. Functional and design specifications are the same thing (Y / N)

16. Kinematics is the study of motion of an object without the regard for forces acting on it (Y/ N)

17. A structure is a body that transforms given input motion to specified output motion (Y/N)

18. A spherical joint is a kinematic pair with three revolute DOF (Y/N)
