Impossible to determine
Explanation:
In other words, no machine can be more than 100% efficient. Machines cannot multiply energy or work input ... If a machine were 100% efficient then it can't have any energy losses to friction, so no friction can be present. In that case the theoretical and actual mechanical advantages would be equal.
