Frame rigidity and steering improvements using diagonal steel strips and torque arms.

so that they are very rigid indeed in the panels.

I have suggested to E.{Mr Elliott - Chief Engineer} that if the frame is later-
ally too flexible for good steering we might use longer
steel strips, thus:

[Diagram showing a central component with 'Torque arms.' extending from the top and bottom, and 'diagonal steel strips.' extending from the corners.]

It will be noticed that one period is about
800 X 3 per rev. = 2400 - i.e. torque reaction, and the
high one 65/70 MPH. probably 1 per rev. = 2500 revs.

For several years I have thought that the torque
arms should be as far forward as convenient - i.e. away
from the body, and direct on the front springs, which are
damped - i.e. not on the flexible part of the frame - I
mean vertically flexible and undamped, as it is under the
dash.

I cannot believe Bentley should be better than
we are except the flywheel whirl, which should be improved
by modifications.
