| To BJ. from Hs.{Lord Ernest Hives - Chair} c. to Wor.{Arthur Wormald - General Works Manager} Y3994 HS{Lord Ernest Hives - Chair}7/LG21.6.26. Y3993 In reply to BJ11/E18.6.26. with reference to BJ3/DN4.6.26. (a) Regarding paragraph (a). We do not think it is necessary to carry out special tests on cars with closed bodies to confirm the results of our previous trial in France. Our reason for this is that the particular test in question was to try the efficiency of the .940 worm and 1800 lbs. side steering tube springs as a means of alleviating the discomfort of customers at present suffering from road shocks. The two main points likely to be affected by this alteration are :- (1) Steering shocks. (2) Car control. We know that steering shocks increase greatly with speed. Also high speed magnifies deficiency in controlability. also that our worst type of cars from the control point of view are those with the least weight over the rear axle. We therefore consider that the cars we tested in France were the type that would give us the best opportunity of experiencing the faults and advantages likely to be obtained from the proposed modification. Experience has shewn us that trying a large number of cars, each with different types of body mk often leads to confusion. Actually on features of a car such as steering, the difference between two chassis may be such that it will still be the controlling factor, no matter what body is fitted. contd:- | ||
