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