| X. 8430 To Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}/HDY{William Hardy}2/M10.7.25. EAC. STEERING - TESTS FOR WORM AND TRUNNION EFFICIENCY. Will you kindly let us have particulars of these efficiencies so that we may calculate the actual losses due to each. The work lost in the trunnions may not be of great importance, although the friction appears to be heavy owing to the small movement that takes place as compared with the worm movement.
