Answer 1

In the context of levers, the class of levers that allows for an increase in the force applied is Class 2 levers.

In a Class 2 lever, the load is located between the fulcrum and the effort, which allows for a mechanical advantage where a smaller effort can move a larger load. Class 1 levers can also offer mechanical advantage depending on the placement of the effort, load, and fulcrum, but Class 2 levers are specifically designed to increase force.

Therefore, the most accurate response for increasing force is:

Class 1 and 2.
