The airframe of an aircraft is its mechanical structure.
Automotive engineering, along with aerospace engineering and marine engineering, is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles and trucks and their respective engineering subsystems.
Body-on-frame is an automobile construction method by which a separate body is mounted on a relatively rigid frame or chassis that carries the engine and drivetrain.
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a pilot controls the aircraft.
An engine or motor is a machine designed to convert one form of energy into mechanical energy.
The floorpan is a large sheet metal stamping that often incorporates several smaller welded stampings to form the floor of a large vehicle and the position of its external and structural panels.
The fuselage (from the French fuselé "spindle-shaped") is an aircraft's main body section.
Monocoque, also structural skin, is a structural system where loads are supported through an object's external skin, similar to an egg shell.
A nacelle is a housing, separate from the fuselage, that holds engines, fuel, or equipment on an aircraft.
Pillars are the vertical or near vertical supports of a car's window area or greenhouse—designated respectively as the A, B, C or (in larger cars) D-pillar, moving from the front to rear, in profile view.
A vehicle frame, also known as its chassis, is the main supporting structure of a motor vehicle, to which all other components are attached, comparable to the skeleton of an organism.
