What are fixed and movable pulleys and give examples of each?
a movable pulley is a wheel and a rope that is used to raise a load
What kind of simple machine is a simple pulley?
It is a rope fitted around the rim of a fixed wheel. Some pulleys increase the force that is applied to them .Other change the direction of the force.They are used to raise and lower things such as elevator cars.It is just that - a pulley.
What would a fixed pulley be used for?
A fixed pulley can be used for certain reasons as for making things easier.
What is used with a pulley to redirect force?
Rope.
Disadvantages of a fixed pulley?
The disadvantage of a fixed pulley is that if it's not fixed in a location where you need it, it's used less.
What is the simple machine used to hoist the flag?
Rope and pulley.

What are two types of pulleys?
There are two basic types of pulleys. When the grooved wheel is attached to a surface it forms a fixed pulley. The main benefit of a fixed pulley is that it changes the direction of the required force. Another type of pulley, called a movable pulley, consists of a rope attached to some surface. The wheel directly supports the load, and the effort comes from the same direction as the rope attachment.

Rope.
Disadvantages of a fixed pulley?

What do fixed fixed pulleys always do?
A fixed pulley when used individually, uses more effort than the load to lift the load from the ground. This is what a fixed pulley always does. When attached to an unmovable object e.g. a ceiling or wall, it always acts as a first class lever where the fulcrum is located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push it up and down. The disadvantage is that you have to apply more effort than the load.
What are facts about pulleys?
Made from a wheel and rope. Used to moved loadsOne interesting fact about a pulley is that Archimedes invented it!a pulley is made from a wheel and a rope
What is the definition of a combined pulley?
fixed and movable pulleys can be combined.
When a fixed pulley is used what does the force and the load do?
A fixed pulley allows the direction of the applied force to be varied. It does not change the load.
