Exercise 24. Ask questions and use the words in italics in your answers. The 
words in brackets will help you.
1. A motor car contains the following components: 
engine, chassis, and 
body
(what components). 2. The power of the engine is transmitted 
through 
the transmission and drive lines
to the wheels (how). 3. The usual source of 
power for a motor car is 
an internal combustion engine
(what). 4. A large capac-
ity diesel should fulfil the following requirements: 
an ability to produce high 
levels of pulling power, reliability, and low fuel consumption
(what requirements). 
5
. Spacing out the main components
in the rear-wheel drive layout makes each 
unit accessible (what).
Exercise 25. Read the following dialogue, sum up the information and act out 
a
similar dialogue.
CHASSIS FRAME
A.: I wonder what a motor vehicle frame is?
B.: A frame is considered to be the main structure of the chassis of a motor 
vehicle. All other components are fastened to it.

A.: It seems to me that now almost all the vehicles are frameless.
B.: I cannot agree with you. In 1920, every motor vehicle besides a few cars 
based on motorcycles had a frame. Since then, nearly all cars have shifted 
to a unitary construction but nearly all trucks and buses still use frames.
A.: Then maybe, you’ll remind me how frame rails are designed.
B.: Sure. There are three main designs for frame rails: C-shaped, boxed, and 
hat.
A.: If I am not mistaken, the most common is the C-shaped frame rail which 
is made by taking a flat piece of steel and rolling both sides over to form 
a C-shaped beam running the length of the vehicle.
B.: You are right. And a boxed frame rail is made by bending a piece of steel 
into four sides and then welding where both ends meet. So the construc-
tion resembles a box.
A.: And I have no idea what a hat frame rail is. What does it resemble? 
B.: A hat frame rail resembles a “U” and may be either right-side-up or in-
verted with the open area facing down. 
A.: Is it commonly used?
B.: You see, they were not commonly used due to weakness, however they 
could be found on 1936—1954 Chevrolet cars and some Studebakers. For-
gotten for a while, the hat frame rail gained popularity again when compa-
nies started welding it to the bottom of unitary construction.
A.: Thanks a lot for your comments. I’d like to continue our discussion a little 
bit later.
B.: You are welcome.
