ASAP A fishing rod is an example of a lever. Which diagram shows the correct positions of the input force, output force, and fulcrum on a fishing rod?

The yellow arrow represents the input force and black arrow represents the output force.
which picture is it?

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
