You are designing a seesaw. If you want one side to have twice the lever arm length as the other, how much force will be needed to balance a 30 kg child sitting on the shorter side, if gravity is acting?
💡 Hint: Consider that torque must be balanced on both sides.
A door is 1.2 meters wide. If you apply a force of 20 N at the edge of the door, calculate the torque produced.
