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 Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
The class 3 lever always has a longer resistance arm than the force arm. This is because the distance from the Fulcrum to the load/resistance is always going to be further that the fulcrum to where the effort/force is applied. If you look at a diagram of a 3rd class lever, you will be able to see why this is.
Bear the load. Bare the load would be to uncover the load...
The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.
load arm, effort arm, load, effort, fulcrum!
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 life the load?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
THE PRODUCT OF LOAD AND LOAD ARM IS CALLED MOMENT OF LOAD.
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
The end of a lever that carries the load is the output arm instead of the input arm which is the end of a lever that force is applied to move the load.
4Explanationfor a lever,effort * effort arm = load *load armso by re arranging above equation,load/effort = effort arm/load armNow, as load/effort is called mechanical advantage so,mechanical advantage = effort arm/load armAs total length of rod is 2 m out of which 1.6 m is effort arm so remaining 0.4 m would be load arm. thus on putting values in the above equation, we getmechanical advantage = 1.6/0.4 = 4
In third class levers effort P is in between the fulcrum F and the load W. According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
lenght of the effort arm divided by lenght of the load arm
