1. The problem statement, all variables and given/known data 2. Relevant equations ok, I thought that the torque from the mass 'm' would be equal to torque from mass 'M' 3. The attempt at a solution I wrote down: m * g * (d/4) = M * g * d (m/4) = M m = 4M Thus, the ratio is 4M : 1 m, which gives answer 1. However, the solutions say that the answer is 5. Could anyone please weigh in, and thanks in advance for the help!
