mechanical advantage (greater or less than 1)in a person rowing a boat

The mechanical advantage of a person rowing a boat can vary. It depends on the specific design of the oars, the shape and size of the boat, and the technique used by the rower.

In general, the mechanical advantage in rowing is often greater than 1. This is because the oars act as levers, with the rower's effort applied through the longer part of the lever (the oar) and the resistance (water) acting on the shorter part of the lever (the boat). By applying a force to the oar, the rower is able to move the boat through the water.

The longer the oars are, the greater the mechanical advantage will be since longer oars increase the lever arm length. Additionally, rowing techniques that maximize the rower's utilization of leg and core muscles can further increase the mechanical advantage.

However, it is important to note that the mechanical advantage of rowing also depends on other factors such as the rower's strength, technique, and the resistance encountered from the water.
