Question

the directions of load and effort are in same directions in Class I lever .But they are opposite in Class II and Class III lever.why?

Answer 1

There are three types or classes of levers, according to where the load and effort are located with respect to the fulcrum. Since humans usually provide energy to levers, "effort" and "load" are often used instead of input and output.

Class 1 has the fulcrum placed between the effort and load. Class 2 has the load between the effort and the fulcrum. Class 3 has the effort between the load and the fulcrum.

Each has its own uses and advantages.
