Learning Outcomes:

Upon completion of this course, students will be able to:

Objective 1

1.1 determine the degree of freedom of a mechanism.

1.2 recognize the various mechanisms in a machine or in a mechanical system and to identify them with the mechanisms commonly used.

Objective 2

2.1 calculate the displacement, velocity and acceleration of the various links of a mechanism using analytical methods such as vectors or complex variables, or graphical methods.

2.2 solve the governing equations numerically by writing their own program or using any available numerical software to perform parametric study to visualize the motions of some linkages.

Objective 3

3.1 identify the forces involved in the various types of gears.

Objective 4

4.1 design simple linkages to transform motion.

4.2 design cams to achieve specified motions of the follower using graphical, analytical and computational methods.

4.3 design a gear train (involving spur, helical, worm, bevel gears and planetary gear trains) to realize a specified speed ratio between specified input and output points, with the analysis of all the forces and torques involved.

Objective 5

5.1 understand the function of common mechanisms not covered in lectures (e.g. Pantograph, swash plate, Wankel engine, variable-stroke pump, differential screw, cluthes, steering linkage, robotic manipulators), and analyze them kinematically by self-learning.
