\\vec{0}`.\u00a0 For an extended object, not only do all the forces need to cancel out, but all the torques must cancel out as well, so that `\\Sigma \\vec{\\tau} = \\vec{0}` also.\u00a0 To work static equilibrium problems for an extended object, we must set up the system of equations showing that all the forces and all the torques acting on the object cancel out.\u00a0 Then we will use our
