What pulley is attached to the load and moves as the load moves Hi I'm Gretchen?

Hi Gretchen, this arrangement to gain mechanical advantage is often referred to as a "block and tackle". It consists of pulleys and ropes, usually not more than four, where the pulley attached to the load moves with the load, and the mechanical advantage is determined by the number of ropes.

Is a movable pulley attached to the load it moves?
Yep.
What is it called when a pulley moves up with the load as it is lifted?
This mainly occurs in a multiple pulley system, but there is no particular name for it.
What class is a pulley?
A fixed pulley with a rope passing through the pulley. The load is attached to one end and a force is applied to the other end.
What is a 1st class pulley?
A fixed pulley with a rope passing through the pulley. The load is attached to one end and a force is applied to the other end.
What is a fixed pulley?
A fixed pulley is a pulley that is attached to a support. It does not reduce the effort needed to lift the load, but rather changes the direction of the applied force.An example of a fixed pulley would be the rope pulley on a well. This is a fixed pulley because the pulley doesn't move (it is attached to the overhead structure).
What are the three kinds of pulley?
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
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.
Ahman is trying to lift an 8-N load that is attached to a fixed 2-pulley system his hands move a distance of 1.6m while the load moves 0.8mwhat force is required?
Assuming the pulleys are frictionless, which they are pretty close to: You have a mechanical advantage of 2, hence your hands move double the distance that the load moves. So you only need half the force, 8N / 2 = 4N.
How can you identify a fixed pulley?
It is set in one position and cannot move. apex :)
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.
Where is the load arm on a pulley?
The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.
