That's an oarlock.
It's a 2nd order lever. Water is pivot, boat is load, arm is effort.An oar is a lever
An oar is a type of Class 3 lever, where the effort (force applied) is between the fulcrum (pivot point) and the resistance (the water the oar pushes against). In this case, the oar handle is the effort, the oar blade acts as the resistance, and the boat acts as the fulcrum.
an oar pin is called thole
The middle part of an oar is called a LOOM
An oar plier, also known as an oarlock or oar clip, is a device used to secure an oar to a boat, allowing the oar to pivot while rowing. It typically consists of a metal or plastic loop or socket that holds the oar in place, enabling rowers to efficiently propel the boat. Oar pliers come in various designs, including those that can be easily adjusted or released for quick removal of the oar. They are essential for maintaining control and stability during rowing activities.
Oar
They act as levers. By placing the oar in the water, the resistance then essentially fixes on end of the oar so it cannot move. Then, the gate at the end of the rigger acts as a pivot point to push the boat past this fixed point
An oar is a type of lever that falls under Class 1 lever. This is because the pivot point (fulcrum) is at one end, the input force is applied at the other end, and the output force (the resistance) is found between the two.
An oar on a boat is considered a second-class lever because the fulcrum (pivot point) is at one end (the oarlock), the effort is applied at the other end by the rower's hands, and the load (the resistance to be overcome, in this case, the water) is in between.
An oar pin is also called a rowlock pin or a thole.
The pivot point of a lever system is called the fulcrum.
