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.
Example of a block and tackle pulley?
A block and tackle pulley system typically consists of two or more pulleys mounted on blocks, with one end of the rope attached to a fixed point and the load attached to the other end. By pulling on the free end of the rope, a person can lift heavy loads with less effort due to the mechanical advantage provided by the system.
What are some common pulley physics problems encountered in engineering and how can they be solved effectively?
Common pulley physics problems encountered in engineering include determining the mechanical advantage of a pulley system, calculating the tension in the ropes or cables, and analyzing the forces acting on the pulley. These problems can be solved effectively by applying the principles of static equilibrium, using free body diagrams to represent the forces involved, and applying the equations of motion to find the desired quantities. Additionally, understanding the concept of friction and its effects on the pulley system can help in solving these problems accurately.
When you want to pull downward to lift something the main advantage of passing a rope upward and through a single pulley rather than just up over the branch of a tree is that the pulley that?
reduces frictionreduces frictionThere is less friction in the pulley than around the branch of a tree so it is easier to lift the object - and easier to drop it too- be careful!A fixed pulley has only one function, to redirect your applied force, Fe."Changes the pulling direction" - (Nothing gained but we do get to pull down instead of lifting upward. This is an advantage and could save your back.)Reduces friction - when using the pulley. - but not what the question is asking.The main advantage is that fricton if reduced, lessening the force required to lift the something. Other "advantages," if any, are secondary.changing the pulling direction...both branch and pulley change the direction of force. What the pulley does is remove the friction of the rope sliding over the branch. Imagine a rope wrapped around the rim of a wheel, and as you pull one end of the rope, the wheel spins. This is the same principle, in that a pulley is made up of grooved wheel and axle, and the rope fits inside of the groove along the rim of the wheel. The wheel rolls freely, removing the friction of the rope moving thru it.
What does a free body diagram of a pulley system illustrate?
A free body diagram of a pulley system illustrates the forces acting on the pulley and the objects connected to it, showing the direction and magnitude of each force.
How is a fixed pulley different from a movable pulley?
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
Why does a fixed pulley provide only a mechanical advantage of 1 how does this type of pulley affect the force?

Is a movable pully fixed at all points?
A movable pulley is not fixed at all points. It has one end attached to a fixed point, such as a ceiling or beam, while the other end is attached to the object being lifted. The pulley itself is free to move along the rope or cable, allowing for mechanical advantage in lifting heavy loads.
What is the advantage of a movable pulley?
a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.

How can an objects weight be used to its advantage?
by using certain mechanical objects, like a pulley, you can use the object's own weight to its advantage. Also, by exploiting gravity and the object's own weight, you can use inertia to roll the object down the hill or yet better in a free fall.
How do you calculate the medical advantage of a movable pulley system?
Mechanical advantage of a movable pulley system can be determined in a number of?æways. The simplest?æ one?æ is by counting the number of rope segments?æ between the pulleys. If the free end is pointing downward do not?æ include. However, you must?æ include if it is pointing in the same direction?æ as to which the load will?æ be moved.?æ
What is moveable pulley?
A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.

How can I create a pulley system?
To create a pulley system, you will need a wheel with a groove, a rope or cable, and an object to lift. Attach the wheel to a fixed point, pass the rope through the groove, and secure one end to the object. Pulling on the free end of the rope will lift the object using the pulley system.
