This document discusses different types of mechanisms that transmit and convert forces and motions. It describes mechanisms as devices that take a driving force as input and transmit or convert that force into motion of an output element. Examples of mechanisms mentioned include gears on a bicycle, clock gears, seesaws, and pulleys. The document also provides a classification of mechanisms based on whether they transmit motion, convert types of motion, or perform linear, rotary, or reciprocating motions.
2. We´re surrounded by objects that move or
have the capacity to move.
ï‚ž The system of gears with a chain for bicycles. The cogwheels of a clock.
The lever of a seesaw. The pulley used to get water from a well.
ï‚ž All of these examples make our lives more confortable and pleasant.
3. ï‚žMechanisms are devices that transmit and
convert forces and motions from a driving
force (input) to an output element.
ï‚žThey enable us to carry out certain tasks
with graeter comfort and less effort.
