Answer 1

The correct response is Class 2 and 3.

In Class 2 levers, the load is between the effort and the fulcrum, which allows you to gain mechanical advantage and thus increase the force. Class 3 levers, while they do not increase force, typically allow for more distance or speed of the load movement. However, Class 1 levers can also vary in their configuration to either increase or decrease force depending on the position of the fulcrum, effort, and load.

Therefore, Class 2 levers are primarily associated with increasing the force applied.
