Question

Determine for which class of lever the output force is always greater than the input force. for which class is the output force always less than the input force?

Answer 1

• Second Class of lever: The second class of the lever is considered the most efficient or have the most mechanical advantage in conveying more productivity or output while investing less input into the system.

Step-by-step explanation:

The second Class of lever:

The second type of lever has the load,L in between the effort,E and the fulcrum,F. As the effort moves a larger distance to move the load a small distance. As there is more productivity or mechanical output in response to less input to the system.

Answer 2

the 3rd class lever is the output force always less than the input force, becuase its mechanical advantage is always less than 1. this also due that in a 3rd class lever the effort arm is shorter than the load arm, that is why the output is lower than the input force. but 3rd class lever is a speed multiplier lever
