1. The problem statement, all variables and given/known data Free body force diagram question, where I have selected the best answer but the diagram doesn't ring completely true (see diagram uploaded). I think mathematically the diagram is sufficient but it doesn't properly represent the situation. Do you agree? 2. Relevant equations 3. The attempt at a solution The normal reaction force must be somewhat counteracting the weight of the climber. So to show the weight perpendicular to the normal reaction force seems very odd, as if they are not linked. Without any weight there would be no normal reaction force. I think this issue would be resolved if the normal reaction force was pointing slightly upward, so the climber would press onto the wall. Does that sound right?
