Pulley can prove that simple machine changes the direction of effort.
The force applied to a simple machine is called effort/input force.
your effort decreases
a lever
is a fixed pulley

a lever
3rd Class lever (Effort in Middle)
3rd Class lever (Effort in Middle)
it lets you work easier with less effort
Any thing that reduces human effort is simple machine whether it is a simple pulley or a complex machine. e.g. axel,gears,transformer,lathe etc,
the law of the machine is an expression which gives the relationship between the load on a machine and the applied effort
Wheel and axle
