It is necessary to have a common point in a circuit that all voltages are referred to. This is necessary because all potentials are relative until they share some common conductor. The common conductor is often called "ground", even if it has no physical connection to earth ground. Your connections are reasonable and proper to make the circuit respond properly to the 40 volt supply.
