Kind of pulley that is not movable?
The major two types of simple pulleys are movable and fixed. An example of a fixed pulley would be a flag pole. The pulley is fixed in place while someone pulls on one end of the rope to lift the flag on the other end, the input force and the output forces being equal in magnitude but opposite in direction.
Are there examples of pulleys in your house?
Pulley belongs to one of the class of Simple machines They are two types of pulleys 1. Fixed pulleys 2. Movable pulleys. Examples Fixed pulley : flag poles, sail boats, simple cranes, curtains in theatres, conveyor belt, simple line elevators Examples Movable pulley : Cranes , amusement park rides , elevators and cable cars using movable pulleys.
How would you use a fixed pulley to lift something heavier than yourself?
You have to have the right size pulley for the weight of the object you want to move and a secure place to attach it. Then, once it's all hooked up, you'll need to generate the force to pull on the rope or cable that will then move your object. If it is more than you can produce with your body, you can attach an engine to it and let it do the work.

Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
WHY IS MOVEABLE PULLEY MORE USEFUL THAN FIXED PULLEY?
A moveable pulley is more useful than a fixed pulley because it allows for a mechanical advantage, making it easier to lift heavy loads. With a moveable pulley, the effort force is reduced as the load force is distributed between the two sections of the rope supporting the load. This results in less force required to lift the load compared to using a fixed pulley.
Why it is easier to lift the same load by using three -pulley system than two-pulley system?
A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.
What is equal to the ideal mechanical advantage of a pulley system?
The ideal mechanical advantage of a pulley system is two times the number of pulleys in the system. This is the amount of force required to get the system moving.
How does pulleys work?
Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.The relationship of Supporting Strands to the Force Multiplier is:(the number of Supporting Strands) - 1So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".
What are 2 kinds of pulleys?
Two kinds of pulleys are the fixed pulley and the movable pulley
What arrangement of moveable and fixed pulleys would give a mechanical advantage of 3?
One fixed pulley and two moveable pulleys would give a mechanical advantage of 3. The rope would go through the fixed pulley, then the first moveable pulley, back through the fixed pulley, and finally through the second moveable pulley.
What are two kinds of pulleys?
A fixed pulley and a movable pulley Block and tackle is made up of both
What is the difference between a pulley and wheel and axle?
there are two kinds of pulleys. A movable pulley and a fixed pulley. But a wheel and axle have a lever and a inclined plane. [someone] :]

What is the 2 kind of pulley?
The two kinds of pulleys are fixed pulleys and movable pulleys. Fixed pulleys are stationary and change the direction of the force applied, while movable pulleys have a free end that moves and both change the direction of the force and provide a mechanical advantage.
Are two types of pulley's?
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.
What are the three kinds of pulley?
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.
