Questions:
- When the reading refers to “blades” what part of the boat is it talking about?
- What are other possible factors that could cause resistance besides drag and wind?
- Would a rower want constant velocity?
- Are oars with larger paddles are more convenient since they can grab more water?
- Do centre of gravity and centre of buoyancy cancel each other out?
- All levers consist of a load, fulcrum, and effort, just in different orders?
- What exactly is the load? The part that fixes the oar to the boat?
Comments:
- Skin drag is most prominent and should be taken into account the most
Hi Aliza! The rower would want constant velocity. This is because instead of taking energy to slow down and speed up, rowing at a constant velocity would take less energy, therefore allowing the rower to focus that energy on improving performance.
Yes, all levers consist of same parts just in different orders/combinations
