A lever system has two different configurations: – The left lever has a mass of 0.5 kg placed 2 meters from the fulcrum. – The right lever has a mass of 1 kg placed 1 meter from the fulcrum. Both levers experience a pulling force of 1 N applied at the same distance from the fulcrum on the opposite side.

Remember how a spring works: when you pull on it, it stretches. Newton’s 3rd Law says that the spring pulls back on you too. If you pull the end of the spring in the +x direction with a force F in the +x direction, the spring stretches by an amount x.
