Consider the following three situations, where a force is applied to a bar that is free to rotate about its center:
A - a force F is applied perpendicular to the bar halfway between the center and one end.
B - a force F is applied perpendicular to the bar at one end.
C - a force 2F is applied perpendicular to the bar halfway between the center and one end.

Rank these situations based on the magnitude of the torque experienced by the bar, from largest to smallest.

1. C>A>B
2. C>B>A
3. C>A=B
4. B>C>A
5. B>A>C
6. B>A=C
7. None of the above

Consider the following three situations, where a force is applied to a bar that is free to rotate about its center. In each case the magnitude of the force is the same and the force is applied to the bar halfway between the center and one end.
A - the force is directed perpendicular to the bar.
B - the angle between the force and the bar is 30°.
C - the angle between the force and the bar is also 30°.

Rank these situations based on the magnitude of the torque experienced by the bar, from largest to smallest.

1. C>A>B
2. C>B>A
3. C>A=B
4. A>C>B
5. A>B>C
6. A>B=C
7. None of the above

Consider the following three situations, where one or two forces are applied to a bar that is free to rotate about its center.
A - the force F is directed perpendicular to the bar and is applied halfway between the center and one end.
B - one force F is directed perpendicular to the bar and is applied halfway between the center and one end; another force F in the opposite direction is applied at the end of the bar.
C - one force F is directed perpendicular to the bar and is applied halfway between the center and one end; another force F in the opposite direction is applied at the far end of the bar.

Rank these situations based on the magnitude of the torque experienced by the bar, from largest to smallest.

1. C>A>B
2. C>B>A
3. C>A=B
4. B>C>A
5. B>A>C
6. B>A=C
7. None of the above
