CLASSIFICATION OF MECHANISMS

A. TRANSMITTING MOTION.

                    - Linear: Lever, Fixed pulley, Movable pulley, Compound pulley.
                    - Rotary: Friction drives, Pulleys with belt, Gear mechanisms, Worm gear, etc.

B. TRANSFORMING MOTION.

                    - Rotary to Linear: Rack and pinion system, Nut and bolt system, Winch and crank handle
                    - Rotary to Reciprocating: Crank-link-slider, Crankshaft, Cam, Eccentric cam

C. CONTROLLING AND REGULATING MOTION.

                   - Disc brakes.
                   - Band brakes.
                   - Drum brakes.

D. STORING ENERGY.

                   - Spring.

E. JOINING ELEMENTS.

                  - Clutch.
                  - Fixed connections.
                  - Movable connections.


EXERCISE : Choose at least three mechanisms and describe them. Include diagrams, pictures, formulas, real applications, etc.You have to do each machine in a single worksheet. 
 It´s not compulsatory. If you do it you can add maximum 0.50 to the final mark of the revision test.
