Well of Death: Physics behind it

[QUOTE="Steve4Physics, post: 6830538, member: 681522"] Yes. The bike has no angular acceleration about its centre of mass. Therefore there is zero net torque about its centre of mass. Since the weight and (fictitious) centrifugal force pass through the centre of mass, the requirement for zero net torque tells us that the net reaction from the wall must also pass through the centre of mass. This is useful as it gives a way to find the angle of the line joiing the point of contact and bike+rider's centre of mass. Yes. That's a perfectly good way to do it. Note that the only forces producing torque about the point of contact are the weight and (fictitious) centrifugal force. EDIT: But of course you need to know the distances ('lever arms') in order to find the torques. [/QUOTE]
