1. The problem statement, all variables and given/known data The maximum torque on a lever is 1.5 x 10^6 Newtons. How many people of weight 750N can stand evenly spaced on this lever, which has a length of 20 meters? 2. Relevant equations T=FR Weight=mg W=Fd X = Number of people 3. The attempt at a solution I have set 1.5x10^6 N = (integral from 0-20) 750X dL. I understand that the correct next step is to divide out the 750, and to integrate the length over the interval 0 to 20. However, I do not quite understand how this method works. Can we assume that X, the number of people, is a constant when integrating?
