Question

Type the correct answer in the box. Spell all words correctly. Ronny wants to calculate the mechanical advantage. He needs to determine the length of the effort arm and the length of the load arm. How can he find the length of the effort arm? The length of the effort arm is the distance between the _____ and the point at which effort is applied.

Answer 1

Fulcrum

Step-by-step explanation:

The length of the effort arm is the distance between the Fulcrum and the point at which effort is applied.

Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys. Despite changing the forces that are applied the conservation of energy is still true and the output energy is still equal to the input energy. Typically the mechanical advantage is expressed in ideal terms, where there is no losses in energy between the input and output times, also known as 100% efficient systems.

By conservation of energy:

Fi×di=Fo×do
