ROTARY MOTION MECHANISMS
Friction drives
The ratio between the rotation veloaty of the wheels or pulleys depends on the relative size of the wheels.
Pulleys with belt
Their axles are parallel and they rotate simultaneously due to the effect of the belt.
Uses: industnal machines, vehicle engines, washing machines and dulls

Pulley trains with belts
The gear rauo between the dnve pulley and the dnven pulley dependson the relauve size of the pulleys in the system. It's expressed as a function oftheir diameters. N4/N1=D1XD3/D2XD4

LINEAR MOTION MECHANISMS
-
Fixed pulley
A fixed pulley is balanced when the effort F is equal to the resistance of the load, R: F=R
-
Compound pulley
This ts a system of fixed and moveable pulleys, often called block and
tackle.
Uses; lifts, goods lifts and cranes
