Answer 1

To answer your question, the class of levers that can increase the force to be applied is Class 1 and Class 2 levers.

• Class 1 levers (e.g., a seesaw or a crowbar) can change the direction and apply a greater force depending on the position of the fulcrum.
• Class 2 levers (e.g., a wheelbarrow) always allow a smaller effort force to lift a larger load.

So the correct response is: Class 1 and 2.
