Rotary motion mechanism 
Pulleys with belt
They consist of two pulleys or wheels that are a certain distance apart. Their axles are parallel and they rotate simultaneously due to the effect of the belt.
-
friction drives: I he ratio between the rotation velocity of the wheels or pulleys depends on the relative size of the wheels. N1 · D1 = N2 · D2

-
Gear train: N4 / N1 = Z1 · Z3 / Z2 · Z4
-
linear motion mechanism
A fixed pulley is balanced when the effort F is equal to the resistance of the load, R:
F = R
A moveable pulley is balanced when it satisfies this equation:
F = R/2

The effort applied is between the fulcrum and the resistance.

The fulrum is between the effort applied and the resistance.

Around us we can see many moving objects and mechanisms that produce movement that we can also call motion.
