The old style of 3-prong dryer cords did not include a ground wire. Changes in the National Electrical Code now require dryers to be wired with a ground wire. This means the cords now have 4-prong plugs.
How do you ground an old dryer?
To ground the dryer, loosen and remove the center screw on the power block. Insert the screw through the hole on one end of the grounding strap and into the hole in the center of the power block. Tighten the screw down. Tighten the other end of the grounding strap under the green screw on the dryer’s frame.

Both neutral and ground are closely related to each other, but a neutral represents a reference point within a power distribution and a return path for the current, whilst ground represents an electrical path designed to carry any fault currents if insulation breakdown were to occur.
Which wire is ground on 3 prong dryer cord?
A 3-wire cord consist of 3 wires molded together. Looking at the cord end without the plug, the left and right wires are the hot wires and the middle wire is the neutral. In a 3-wire circuit, the neutral also acts as ground.
