Answer:
1/ 485.6 Nm
2/ Clock-wise
3/ 0 and no direction
4/ 1.62 m
Explanation:
1/ Torque is gravity force times the moment arm. Let's g = 9.81m/s2
2/ If person 2 is sitting on the right, the direction of this torque is clock-wise, since the gravity is acting downward.
3/ Assuming that location A is right at the pivot point, then the torque generated by this torque is 0, since the moment arm is 0. This has no direction.
4/ The seasaw is balanced, this means torques generated by 2 people are equal and in opposite direction
So the new location for d2 is 1.62m
