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 .
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.
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).
Bear the load. Bare the load would be to uncover the load...
