of all steel construction.
Doors derive most of their strength from the
inner panel. The inner panel acts as a frame for the door. It is made with
offsets and holes for the attachment of inner door hardware.
The outer
panel flanges over the inner panel edges to form a single unit.
It also
provides an opening through which the outside handle protrudes.
In some
instances, a separate opening is provided for the lock.
(7) Deck Lid. The deck lid is another door that allows access to the
luggage compartment. It consists of an outer and inner panel. These panels
are spot welded together along their flanged edges to form a single unit.
b.
Frame Construction.
(1) An understanding of the construction of the frame is extremely
important, since it is the foundation on which the vehicle is built. Frames
of all types to fit all conditions are described and illustrated in this
section.
Frames can be constructed from channel stock, I-beam, angle, T-
stock, Z-stock, tubing, flat plates, or a combination of any two or more of
these stocks. Frames are usually wider at the rear than the front. This
permits a shorter turning radius by allowing more room for the front wheels.
It also allows more space for supported load carrying at the rear.
The
heaviest cross member is usually mounted under the front portion of the
engine.
