1. The problem statement, all variables and given/known data A massless stick of length d, held parallel to the ground, has a mass, m, attached at one end of it and a pivot on the other end. A second mass, m, is glued on at a distance x from the pivot. At what distance x would maximize the angular acceleration of the stick the instant it is released. 2. Relevant equations F=Ma Τ=Iα=RxF a=αR 3. The attempt at a solution I found the center of mass position, R, to be x+(d-x)/2 and F=2mg. With some algebra I found that Τ=2m(x+(d-x)/2)²α=2mg(x+(d-x)/2) Then solving for α, I found α=g/(x+(d-x)/2) and to maximize I would have to take the derivative with respect to x and set it equal to zero. I believe this work to be right but my friend brought up the fact there would be a tensile force in the stick and I don't know how that would affect the equations if it would at all.
