The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.

What jobs did the pulley do?
A pulley is a wheel with a groove on its edge for holding a rope or cable. pulleys are usally used in sets desinged to reduce the amount or force needed to lift a load.
To calculate a load to see what size footing you need for a crane If you were to have a 1000lb load on a 21' boom that is 14' above the ground what is the load on the base of the crane?
You will need a footing to support a moment of 21,000 ft.lbs.Moment = Arm x ForceMoment = 1000 lbs. x 14 ft. = 21,000 ft.lbs.
What type of pulley can you use to change the direction of the effort force?
Fixed Pulley and Compound Pulley.
What is a movable pulley?
a pulley that is attached to the resistance and moves with it
Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
Is a arm a pulley?
no
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
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.
What are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
What is a load arm?
Answerer: The load arm is a balanced mechanical arm use mainly at jetties to load and discharge petroluem or chemicals to a tank onshore. It is used at truck loading bay as well. Editor: The load arm is a balanced mechanical arm use mainly at jetties to load and discharge petroluem or chemicals to a tank onshore. It is used at truck loading bay as well. Also the load arm is the part of a lever where the load is applied, which is the opposite of effort arm which is where the effort or work is applied.
A load can be lifted easily by?
A load can be lifted easily by using a pulley system.
What is the definition of the resistance arm?
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
When the load is at a constant position on the lever arm how can you make it easier to lift the load?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
How can you make it easier to lift the load when the load is at a constant position on the lever arm?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
Define moment of load?
THE PRODUCT OF LOAD AND LOAD ARM IS CALLED MOMENT OF LOAD.
When th load is at a constant position on the lever arm how can you make it easier to lift the load?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
What do we use a fixed pulley for?
this is berat writing.we use fixed pulley for lifting load up only by using force on the effort that makes the load lift
