Non-integrability criteria, based on differential Galois theory and requiring the use of higher order variational equations (VEk), are applied to prove the non-integrability of the Swinging Atwood's Machine for values of the parameter which can not be decided using first order variational equations (VE1).

Non-integrability of the degenerate cases of the Swinging Atwood's Machine using higher order variational equations
