You know how it's harder to push a door if you're pushing from closer to the hinges, rather than at the doorknob? This game plays with the same fundamental physics! The idea is to solve for the unknown mass with a smiley face on it by using the knowledge of the placement of each other mass, relative to the pivot point of the bar it rests on (easy!). Some masses are not given but can instead be solved for. I highly recommend to not just guess. Try to do the math here! This is the only equation you will need: τ = F × r × sin(θ) Have lots of fun! You have 5 guesses and there are three levels, each harder than the last. Enjoy!
