Question

Which option correctly describes the relationship between simple machines, a lever, a fulcrum, effort, and load?(1 point)
Responses

A simple machine is a type of lever made of a bar that pivots on a fixed point called a load, which reduces effort needed while producing more work to move a fulcrum.

A lever is a type of simple machine made of a bar that pivots on a fixed point called a fulcrum, which reduces effort needed while producing more work to move a load.

A fulcrum is a type of lever made of a bar that pivots on a fixed point called a load, which reduces effort needed while producing more work to move a simple machine.
A fulcrum is a type of lever made of a bar that pivots on a fixed point called a load, which reduces effort needed while producing more work to move a simple machine.

A load is a type of lever made of a bar that pivots on a fixed point called a fulcrum, which reduces effort needed while producing more work to move a simple machine.

Answer 1

The second option is correct:

"A lever is a type of simple machine made of a bar that pivots on a fixed point called a fulcrum, which reduces effort needed while producing more work to move a load."

(Brief note: more precisely, a lever reduces the effort needed by trading force for distance — it doesn't create extra work, it changes the required force to move the load.)
