LINEAR MOTION MECHANISMS
These transmit motion and force in a straight line from one point to another for example lever or a pulley
-
a lever is a rigid bar that is used with a point of support or a fulcrum .The mechanical force or effort is applied on one end of the lever

FIXED PULLEYS
A fixed pulley is a wheel that has a groove for a rope,chain or belt to go around it it rotate aroundan axle that is fixed to an inmobile surface
-
pulleys are used to raise and lower loads easily because we use our own weight to counteract them

MOVEABLE PULLEY
-
-
The effort needed to move a load with a moveable pulley is half of the effort needed with a fixed pulley. This type of pulley means we can lift weights with less effort.
COMPOUND PULLEY
This is a set of fixed an moveable pulleys, often callled a block and tackle if we use more pulleys it becomes more complex, but less effort is needed to move the load
