Sports
Quick fact
In rowing, the oar is a first-class lever where the effort arm (handle to oarlock) is typically shorter than the load arm (oarlock to blade), giving a mechanical advantage less than 1—meaning rowers pull hard to make the blade move fast.
Why this is interesting
Ever wondered why rowers adjust the oarlock position so carefully? The long oar is actually a clever lever system that trades force for speed.
