(Fixed pulleys and Moveable
pulleys)
- hoists
- Set of moveable
and fixed
pulleys.
- rotary transmission mechanisms
- friction wheels
- a set of two wheels located one
next to the other. Motion is
transmitted between the wheels
by friction.
- gears
- Mechanism consisting of
two toothed wheels.
- belt and pulley
system
- Two pulley wheels
joined by a belt that
slots into the grooved
rim of the wheels.
- chain and
sprocket
systems:
- Two toothed wheels
(sprockets) separated by a
distance and connected by a
chain that meshes with the
teeth of the two wheels.
- motion conversion mechanisms
- Device that transmits and/or convert motion.
