It is an effort machine
Those kinds of devices are called machines.
It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
which pulley changes the direction of force
A fixed pulley changes the direction of the force.

It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
moment depends upon the force and the perpendicular distance between the force and the point where we are finding the moment. so when moment changes either the force will change or the perpendicular distance will change.
changes the direction of a force
which pulley changes the direction of force
when it changes its direction
A fixed pulley changes the direction of the force.
It changes the direction of the input force only
Force changes either the speed or the direction of motion, or both.
The combined changes in an object's speed and direction when force acts on it is called "acceleration".
