| 1306. Rm {William Robotham - Chief Engineer} /FWK. from Rm. {William Robotham - Chief Engineer} Rm {William Robotham - Chief Engineer} 5/R.13.5.39. Your note re spring failures is interesting. We should like to know whether the shackle angle has any effect on the stress in the top leaf, and if not, whether you can make any suggestions for evening out the stress range to which different portions of the top leaf is subjected.
