Few similarities between different types of lever are All levers are fixed in a point called fulcrum. They make our work easier. They change the direction of force .....

In second class lever load is situated between fulcrum and effort. So , distance from fulcrum to load I.e load distance is less than effort distance. We know, load x load distance = effort x effort distance or, load / effort = effort distance / .....

Velocity ratio is the ratio between distance covered by effort to the distance covered by load. We know, value of distance is always positive. So ratio between two quantities is also positive. Therefore velocity ratio is always .....

In third class lever  effor is always between fulcrum and load. in this figure, we can clearly see that effort distance is smaller than load distance. we know velocity ratio is effort distance divided by load distance. Since effort .....
