A first-class lever has the fulcrum located:

Three classes of levers, distinguished by the positions of fulcrum, effort, and load: (1) FIRST-CLASS: fulcrum is BETWEEN effort and load. Examples: seesaw, scissors, crowbar, pliers, claw hammer pulling nails. Effort and load move in opposite directions. Mechanical advantage can be >1, =1, or <1 depending on lengths. (2) SECOND-CLASS: load is BETWEEN fulcrum and effort. Examples: wheelbarrow, nutcracker, bottle opener, door (hinge=fulcrum, doorknob=effort, weight=load). Always provides mechanical advantage >1 (force multiplier). Effort and load move same direction. (3) THIRD-CLASS: effort is BETWEEN fulcrum and load. Examples: tweezers, fishing rod, broom, human forearm (elbow=fulcrum, biceps=effort, hand/load = third class). Always has mechanical advantage <1 (speed multiplier — gives distance/speed at cost of force). Effort and load move same direction. Mnemonic 'F-L-E' for what's in the MIDDLE: First class = Fulcrum middle; second class = Load middle; third class = Effort middle. Mechanical advantage = effort arm length ÷ load arm length. ASVAB MC frequently asks identification and MA calculation.
