All of the statements provided are true regarding an extended free-body diagram (eFBD).

1. All of the forces acting on a system that would show up on a regular FBD should also be on an eFBD: This is true because an eFBD is simply an extension of a regular free-body diagram (FBD). It includes all the forces acting on a system, just like a regular FBD, but also includes additional information such as the points of application of the forces and the distances between these points.

2. Each force vector acting on a system should have its tail placed at the location where that force is applied: This is true because the location of the force application is important in an eFBD. It helps in understanding the rotational effects of the forces.

3. The choice of axis to sum the torques about is determined by you: This is true because the choice of axis is arbitrary and can be chosen for convenience. The physics of the system does not change with the choice of axis.

4. Certain choices of an axis to sum the torques about will prove more advantageous when solving the system: This is true because choosing an axis where many forces pass through or where the distances to the forces are simple can simplify the calculations.

5. The lever arm for a particular force points from the chosen axis to the point where the force is applied: This is true because the lever arm is defined as the perpendicular distance from the axis of rotation to the line of action of the force. It is used in calculating the torque produced by the force about the chosen axis.
