MECHANIMS
3.1. Friction drivers
I he ratio between the rotation veloaty of the wheels or pulleys depends on
the relative size of the wheels.
It is expressed by the followmg equation:
N1·D1=N2·D2 - D1/D2=N1/N2
N1 and N2 are the velocities of the primary drive wheel and the
output wheel
D2 and D2 are the corresponding diameters
They are expressed in units of length: usually millimetre
3.2. 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.

3.6. grear train
The gear ratio between the drive wheel (I) and the dnven wheel (4) depends
on the number ol geared teeth m the system
N4/N1= Z1·Z3/Z2·Z4

2.LINEAR MOTION MECHANIMS: Mechanims that transmit motion and force in a stright line from one point to another.
-
2.2. Fixed pulley
A fixed pulley is balanced when the efoort F is equal to the resistance of the load, R
F=R
-
2.4. compouns pulley
This is a system of fixed and moveable pulleys, often called block and
tackle.
-
-
around us we can see many moving objects and mechanims that produce movements that we can also call motion.

-
Mechanims are devides that transmit and convert forces and motion from a driving force or inpuut element to and output element.
they allow us to carry out certain tasks more easily and more efficienly
