Bailey - Chief Engineer} c. RG.{Mr Rowledge} OY. DA.{Bernard Day - Chassis Design} RE BRAKE TESTS. Attached herewith is a report on the analysis of the 20 H.P. footbrake. The brake was fixed to the back end of a Froude water brake; driving the brake was a 20 H.P. engine unit. It was arranged that we could vary the load on the brake and measure the torque. The results are comparative. We are improving the test tackle. Hs.{Lord Ernest Hives - Chair} | ||
