A farmer is trying to lift the corner of a large water tank. She uses a metal rod as a lever. The vertical force from the farmer is constant and is always applied to the end of the rod. Which change must increase the upward force on the water tank?

1. Ausing a longer rod and moving the pivot closer to the tank
2. Busing a longer rod and moving the pivot further away from the tank
3. Cusing a shorter rod and moving the pivot closer to the tank
