Where to Sit to Balance a SeeSaw? | Torque & Static Equilibrium

Given the mass and position of one person, find where to place another person given only their mass such that the see saw, or teeter totter is balanced.
Ultimately this problem is a statics problem, meaning that we are trying to keep the beam from rotating. This means the sum of all torques, or NET TORQUE on the see saw needs to be zero.
Working out expressions for the torque by each person, then setting those torques equal to each other, we can solve for the position of the second person.
This problem typically comes up in introductory physics courses including high school physics as well as entry level college physics.

😢is this second equilibrium of rigid body? If not what is the formula for equilibrium of rigid body. Thanks

Yes. Solving for the force by the fulcrum would be the 1st condition.

Howd you get the 735N and 245N

75x9.8 and 25x9.8 (the weight of each person)

No weight for the see-saw?? No normal force from the pivot point?

Made the seesaw massless to simplify the problem. Normal force from the pivot will not produce any torque around the pivot point and therefore will not influence the outcome.
