A basic mechanical purchase using a single block to redirect a line and gain a two-to-one mechanical advantage. Riggers set up a whip by securing one end of a rope to a fixed point, passing it through a movable block attached to the load, and pulling the free end. It is the simplest form of block and tackle used aboard ships for light lifting tasks.
Rig a whip on that halyard so we can hoist the barrel without breaking our backs.
When a whip is inverted so the block is fixed and the load is on the running end, it loses the mechanical advantage and merely changes the direction of pull.
