Physics of Rowing :: physics row boating

Missing FiguresMarathon runners talk about hitting the wall at the twenty-thirdmile of the race. What rowers confront isnt a wall its a stack - anabyss of pain, which opens up in the second minute of the race. Largeneedles ar being driven into your thigh muscles, while your fore munition followmto be splitting. thusly the pain becomes confused and disorganized, notlike the windedness of the runner or the branching burn of the biker merely anall-over, savage unpleasantness. As you pass the five-hundred-meter mark,with three-quarters of the race as yet to row, you realize with dreadthat you argon not going to make it to the finish, but at the same time theidea of letting your teammates down by not rowing your hardest isunthinkable...Therefore, you are going to die. Welcome to this life.-- Ashleigh TeitelThe BasicsThe cavort of rowing involves numerous combinations and classes of athletes. Boats can be rowed with or without coxswains (the non-rowing captain) and by 1, 2, 4, or 8 rowers. Each rower can handle one oar (sweeping) or two oars (sculling). Racing instances are currently being made with vitamin C or Carbon/Kevlar combinations. The act of rowing involves the transfer of momentum by the rowers and their oars to the wet. The momentum is transferred to the water by pulling on the oar and pushing with the legs (the feet are attached to the boat by restraints). This causes the seat to slide backwards and the oars to pin tumbler on the riggers. Each slash is made up of four staple parts catch (blade just in the water, knees bent, arms forward), drive (legs straight, arms pulling toward the body), finish (oar out of water, blade vertical), recovery (body moves forward, blade turns from vertical to the horizontal). For some of the basic forces acting on a 4+ (coxed four) see Figure 1.Figure 1 mx is the mass for each rower x (1-4) and coxswain (c), M is the mass of the boat, and Fx (x=1- 4) is the force exerted by the stroke and Fdrag is the resistiv e force of the water. DragDrag is the transfer of momentum from our piteous object to a fluid. A crew moves through both water (in contact with the shell) and air (in contact with a small part of the shell and the rowers). Effect on CrewTo minimize air resistance rowers stick out skimpy unis and force their coxswains to lay in the very short and differentiate stern of the boat.
