James Clerk Maxwell,
A Problem in Dynamics
“ AN inextensible heavy chain Lies on a smooth horizontal plane, An impulsive force is applied at A, Required the initial motion of K. Let ds be the infinitesimal link, Of which for the present we've only to think; Let T be the tension and T + dT The same for the end that is nearest to B. Let a be put, by a common convention For the angle at M 'twixt OX and the tension ”
